Unit 7 polygons and angles is a unit that focuses on identifying and constructing different types of polygons and angles. Specifically, students must be able to identify triangles, quadrilaterals, pentagons, hexagons, heptagons, octagons, and nonagons, as well as identify right, acute, obtuse, and straight angles.The measure of each angle of a regular n-gon is (n-2)*180/n. Polygon Exterior Angle-Sum Theorem. The sum of the measures of the exterior angles of a polygon, one at each vertex, is 360. If a quadrilateral is a parallelogram then, its opposite sides are ______________. congruent.Explanation. The sum of the angles in a triangle is always 180 degrees. In this case, we are given three angles: 70, 25, and 80. To find the missing angle, we subtract the sum of these angles from 180. 70 + 25 + 80 = 175. Therefore, the missing angle is 180 - 175 = 5 degrees. However, this answer contradicts the given answer of 70, so there may ...A quadrilateral with two pairs of consecutive sides congruent and no opposite sides congruent. leg.

The interior angle sum of any polygon can be found using the formula (n-2) * 180, where n is the number of sides of the polygon. In the case of an octagon, which has 8 sides, the formula becomes (8-2) * 180 = 6 * 180 = 1080 degrees. Therefore, the correct answer is 1080.
