Geometry Unit 4

3. Triangles that have the same size and shape. All corresponding sides and angles are congruent.
6. A triangle with at least two congruent sides.
9. (Angle-Side-Angle):If two angles and the included side of one triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.
10. A statement that shows corresponding vertices of congruent triangles in the correct order.
11. (Angle-Angle-Side):If two angles and a non-included side of one triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.
12. A triangle with one right angle (one angle measures exactly 90∘).
13. A triangle with one obtuse angle (one angle measures greater than 90∘).
15. (Hypotenuse-Leg):If the hypotenuse and one leg of a right triangle are congruent to the hypotenuse and corresponding leg of another right triangle, then the triangles are congruent.

1. A triangle with three congruent sides and three congruent angles.
2. The sum of the measures of the interior angles of a triangle is 180∘.
4. (Side-Side-Side):If all three pairs of corresponding sides of two triangles are congruent, then the triangles are congruent.
5. If two sides of a triangle are congruent, then the angles opposite those sides are congruent.
7. A triangle with three acute angles (all angles measure less than 90∘).
8. A triangle with no congruent sides.
14. (Side-Angle-Side):If two sides and the included angle of one triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.
