Geometry Congruent triangles
| Question | Answer |
|---|---|
| Third Angle Theorem | If two angles of one triangle are congruent to two angles of another triangle, then the third angles are congruent. |
| legs of an isosceles triangle | the congruent sides of an isosceles triangle |
| base of an isosceles triangle | The non-congruent side of an isosceles triangle |
| Vertex Angle of an isoscels triangle | the angle formed by the two congruent sides of an isosceles triangle |
| Base Angles of an isosceles triangle | The congruent angles adjacent to the base of an isosceles triangle. |
| Isosceles Triangle Theorem | If two sides of a triangle are congruent, then the angles opposite those sides are congruent. |
| Theorem: Equilateral triangles | The angles of an equilateral triangle are all 60 degrees. |
| Hypotenuse of a triangle | The longest side of a right triangle. |
| Legs of a triangle | The two sides of the right triangle other than the hypotenuse. These sides form the right angle. |
| Scalene triangle | A triangle with no congruent sides |
| Isosceles Triangle | A triangle with 2 congruent sides |
| Equilateral triangle | A triangle with THREE congruent sides |
| Acute triangle | A triangle with 3 acute angles |
| Obtuse triangle | A triangle with ONE obtuse angle |
| Right triangle | A triangle with ONE right angle |
| Equiangular triangle | A triangle with 3 congruent angles (all are 60 degrees) |
| Perpendicular bisector | a line that is perpendicular to a segment and goes through its midpoint(bisects the segment) |
