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) |
