Show all the shapes and all the interior angles. As students drag the vertices of the triangle to change its shape, the individual angle measures will change, but the sum of the measures will remain 180° for the interior angles and 360° for the exterior angles. Theorems include: measures of interior angles of a triangle sum to 180°; base angles of isosceles triangles are congruent; the segment joining midpoints of two sides of a triangle is parallel to the third side and half the length; the medians of a triangle meet at a point. Note: You can find the interior angle of a regular polygon by dividing the sum of the angles by the number of angles.
