WebTriangle Exterior Angle Theorem An exterior angle of a triangle is equal to the sum of the two opposite interior angles. The sum of exterior angle and interior angle is equal to 180 … WebTrue. A square has four fight angles and four equal sides, so it is a regular polygon. True. If a triangle is an obtuse triangle then it can not be an isosceles triangle. False. If a triangle is a right triangle, then the other two angles must be acute. True. sum of exterior angles of any polygon is always 180°. False.

WebAn equilateral triangle is a triangle that has all its sides with the same length and all its interior angles with the same measure. This means that all of its exterior angles also have the same measure. Since the sum total of the exterior angles equals 360°, we can divide by 3 to get the measure of each exterior angle in an equilateral triangle. WebAll interior angles of a triangle are more than 0° but less than 180°. The bisectors of all three interior angles intersect inside a triangle at a point called the in-center, which is the center of the in-circle of the triangle. The sum of each interior angle and exterior angle is equal to 180° (straight line).
