### UNIT 4 CONGRUENT TRIANGLES HOMEWORK 3 ISOSCELES AND EQUILATERAL TRIANGLES ANSWERS

Triangle Sum Theorem The sum of the measures of the interior angles of a triangle is o. How to identify different types of triangles. Corollary to Theorem 4. That means as you rotate by counting angle, then side, then angle, then side, then angle, and then side you cannot miss two pieces in a row! Apply the properties of congruence to triangles. Share buttons are a little bit lower. Be sure the pattern that you find fits the same pattern in the same way from the other triangle.

Triangle Sum Theorem The sum of the measures of the interior angles of a triangle is o. Angle-Angle-Side Congruence If two angles and a nonincluded side of one triangle are congruent to two angles and the corresponding nonincluded side of the second triangle, then the two triangles are congruent. These are said to be adjacent to a specific side. So we need to keep them separate The three original angles are called interior angles because they are inside the triangle. Download ppt “Chapter 4 Congruent Triangles.

So you must verify that when the triangles are drawn in the same way, what pieces match up? Hypotenuse-Leg Congruence Congfuent If the hypotenuse and a leg equilatrral a right triangle are congruent to the hypotenuse and a leg of a second right triangle, then the two triangles are congruent.

The three new angles are called exterior angles because they lie outside the triangle. The statement is true because of SSS Congruence. Rotate around the triangle keeping one thing in mind. The statement is not true because the vertices are out of order. Converse of Base Angles Theorem If two angles of a triangle are congruent, then the sides opposite them are congruent.

DAVID SAWTELL THESIS

Angle-Angle-Side Congruence If two angles and a nonincluded side of one triangle are congruent to two angles and the corresponding nonincluded side of the second triangle, then the two triangles are congruent. Corresponding, remember, means that objects are in the same location. The third side is called the base.

## Chapter 4 Congruent Triangles.

Side-Side-Side Congruence Postulate If three sides of one triangle are congruent to three sides of a second triangle, then the two triangles are congruent. That means as you rotate by counting angle, then side, then angle, then side, then angle, and then side you cannot miss two pieces in a row! The side opposite the right angle is called the hypotenuse.

Triangle Sum Theorem The sum of the measures of the interior angles of a triangle is o.

We think you have liked this presentation. Use the Distance Formula to verify congruent triangles.

Angle-Side-Angle Congruence If two angles and the included side of one triangle are congruent to two angles and the included side of a second triangle, then the two triangles are congruent. This is treated just like a theorem or uint postulate in proofs. Exterior Angle Theorem The measure of an exterior angle of a triangle is equal to the sum of the measures of the two nonadjacent interior angles.

Introduction Isosceles triangles can be seen throughout our daily lives in structures, supports, architectural details, and even bicycle frames.

No Reflexive Property of Congruence Yes! If it fits, they are congruent. My presentations Profile Feedback Log out. Apply the properties of congruence to triangles. Side-Angle-Side Congruence Postulate If two sides and the included angle of one triangle are equjlateral to two sides and the included angle of a second triangle, then the two triangles are congruent.
