| Question | Answer |
| It is a triangle that has at least two congruent sides | Isosceles Triangle
|
These are the sides of the triangle called | Legs
| It is an angle formed by the legs | Vertex angle
| It is the opposite of the vertex angle | base
| Two angles that have the base as a side | base angle
| It is the symbol used to determine that two angles are the same | Congruent
| It is the result that has been proven to be true | Theorem
| It is located at the other end, side or corner of something | opposite
| These are lines that formed a right angle | Perpendicular Lines
| One of the parts into which something can be divided | segment
| A point where two lines that meet to form an angle | Vertex
| It is also known as the height of the triangle | Altitude
| It is a line segment drawn from a vertex to the midpoint of its opposite side | Median
| It is an angle drawn from a vertex that bisects the vertex angle | Angle bisector
| It is the perpendicular bisector of each of a triangle | Mediator |
