Aug 06, 2011 · Since 3 and 5 are not alternate exterior, alternate interior or corresponding angles, they are not guaranteed to be equal. However, since 3 and 4 make a straight angle (180 degrees) and 4 and 5 are alternate interior angles (which means they are equal), we can find the measure of 3.
Feb 23, 2018 · Explore 1 Exploring Interior Angles in Triangles You can find a relationship between the measures of the three angles of a triangle. An interior angle is an angle formed by two sides of a polygon with a common vertex. So, a triangle has three interior angles. Use a straightedge to draw a large triangle on a sheet of paper and cut it out.
