In a triangle, the measure of the largest angle is 12 less than the sum of the measures of the other two angles. The largest angle is also 52 more than the twice the middle angle decreased by three times the sm
The sum of angles in a triangle is always 180 degrees. The sum of angles in a quadrilateral (four-sided figure) is always 360 degrees. Based on their measurements, angles are classified as acute, right, obtuse, straight, or reflex. In a right triangle, one angle is exactly 90 degrees,...

Interior and Exterior Angles of a Triangle Lesson Summary Frequently Asked Questions Do exterior angles add up to 360? Yes, the sum of the exterior angles for all polygons, no matter the number of sides/angles, will always be 360 degrees. What is interior angle with example? In a polygon...
Thesum of an interior angle and the exterior angle on the same vertex is always 180° since they form a linear pair. What is the sum of all interior angles of a quadrilateral? The formula used to find the sum of the interior angles of a polygon is: S=(n-2) × 180°. In this ...
