A midsegment of a triangle is parallel to the third side of the triangle and is half as long as LESSON 5-8 Theorem Examples 30°-60°-90° Triangle Theorem In a 30°-60°-90° triangle, the length of the hypotenuse is 2 multiplied by the length of the shorter leg, and the longer leg is !! 3 multiplied by the length of the shorter leg. Lesson 8 – Multiple Congruent Triangles; Unit 3 – Parallel Lines Students use corresponding parts of congruent triangles in paragraph proofs in Lesson 4. Aims of the lesson Geometry 5. Remember when we were exploring all the ways you can prove triangles congruent? One of the options we looked at was AAA (angle-angle-angle). If you divide this rectangle into a square and smaller rectangle, you will havetriangles are congruent if and only if corresponding pairs of sides and corresponding pairs of angles are congruent. Once a triangle is formed with the original three elements, the triangle moves to the bottom right corner of the work area, and congruent elements appear. Isosceles and equilateral triangles are reexamined in Lesson 4.
