The polygon sum formula states that for any n−gon, the interior angles add up to (n − 2) ×180∘.Remember, the sum of the interior angles in a pentagon is 180 (5.
We know that each exterior angle is supplementary to the interior angle.Now, the area of a triangle is half of the base times height, so:1.12 polygons and symmetry 1.
Interior angle and exterior angle make linear pair.= 180(n − 2) where n is equal to the number of sides of the regular polygon.
A concave polygon, to the contrary, does have one or more of its interior angles larger than 180°.The formula for the sum of the interior angles of any regular polygon is as follows:Observe that the interior angle of a polygon is equal to 1800 minus the exterior angle of the polygon.
The angle i've marked $\varphi$ is one of the interior angles of the regular polygon created by the line segments, and we can work out the interior angle of such a polygon:Learn more about the angles in a pentagon through the solved.
Sign in • join aops • blog info.Since this is a regular decagon, all of the angles are equal, so divide.Let us take an example to understand the concept better, for an equilateral triangle, n = 3.
How many sides does the po.Area of one triangle = base × height / 2 = side × apothem / 2.
Therefore, the sum of exterior angles of a polygon = n (360°/n).Now, we've seen previously that there is a formula for calculating the sum of the interior angles in any polygon.A regular polygon is a polygon in which all sides are equal and all angles are equal, examples of a regular polygon are the equilateral triangle (3 sides), the square (4 sides), the regular pentagon (5 sides), and the regular hexagon (6 sides).

PITTSBURGH -- — Pedro Pages doubled home pinch runner Michael Siani and then scored on Alec Burleson's RBI single as the the St. Louis Cardinals edged the Pittsburgh Pirates 3-2 in 10 innings on Thursday. St. Louis took two of three from its NL Central Division rivals by winning a series finale for the 12th time in its last 13 chances — one of the reasons the Cardinals are 30-17 since May 12, the third-best record in the majors over that span. “It’s important,” St. Louis manager Oliver Marmol said. “You feel good heading to the next city, mood wise, just all of it. It carries you through.” Burleson and Dylan Carlson had two hits apiece for St. Louis. John King (3-1) retired Andrew McCutchen with the tying run on second in the 10th to pick up the victory for the Cardinals, who improved to 16-12 in one-run games this season after going 17-26 in tight contests a year ago. St. Louis starter Andre Pallante worked a career-best seven innings to give the Cardinals' overextended bullpen a little bit of a breather. Pallante struck out five against one walk, his only wobble coming when Bryan Reynolds led off the fourth with his 14th homer of the season for Pittsburgh. “I mean, definitely the confidence has been snowballing in the last couple of outings and just having confidence with my pitches and the way that they're going,” Pallante said. Reynolds' homer was the highlight for the Pirates, who managed just seven hits total. Nick Gonzales provided an unusual sacrifice fly in the bottom of the 10th, hitting a drive to the notch in left-center field that St. Louis left fielder Brendan Donovan tracked down. Donovan, however, hesitated while getting the ball in, allowing pinch runner Michael A. Taylor to score from second. Jared Triolo and Joey Bart followed later in the inning with consecutive two-out singles but McCutchen grounded into a fielder's choice to end it. Dennis Santana (2-1) took the loss when Pages hit a liner to left-center that a diving Taylor couldn't grab, scoring Siani. Burleson followed with a bloop that let Pages chug home from second. The Cardinals went 0 for 8 with runners in scoring position and left six men on base through the first nine innings, including two in the ninth when pinch-hitter Matt Carpenter struck out looking with the go-ahead run just 90 feet away. They survived thanks in part to gritty work by King and Andrew Kittredge, who struck out Reynolds at the end of an 11-pitch at bat in the eighth with the go-ahead run on second. Martin Perez worked in and out of trouble over 7 1/3 innings for the Pirates in his second start back from a month-long stay on the injured list with a left groin problem. Perez allowed one run on six hits, with a walk and two strikeout and showed a rare burst of emotion when he pumped his left first after fanning Paul Goldschmidt to end the sixth. “I was able to move the ball where I wanted and make some pitches,” Perez said. “It was a great game. We played good. That’s what happens, they were just lucky at the end, but that’s part of the game.” TRAINER'S ROOM Pirates: Placed rookie pitcher Jared Jones on the 15-day injured list on Thursday with a right lat strain. Jones, who will out until after the All-Star break, complained of discomfort in his right side while working five innings against the Cardinals on Wednesday. ...
