Since congruent triangles have the same shape, their corresponding angles are congruent. In this project, students demonstrate their understanding of triangles (trigonometry, special right triangles, Pythagorean theorem, triangle congruence and similarity) by writing a children's book. Theorems include: measures of interior angles of a triangle sum to 180 degrees; 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. Congruent figures. 3 Third Angles Theorem: If two angles of one triangle are congruent to two angles of another triangle, then the third angles are also congruent. They also write a summary comparing and contrasting the triangle congruence theorems. Therefore, any two triangles can be superimposed side to side and also angle to angle.
