triangles

2. a line segment joining a vertex to the midpoint of the opposite side, thus bisecting that side
6. congruence theorem stating that if two triangles have two equal angles and a side adjacent to only one of the angles that are equal, then the two triangles are congruent
9. the longest side of a right-angled triangle, opposite the right angle.
10. congruence theorem stating that two triangles are congruent if two sides and the included angle of one triangle are equal to the two sides and the included angle of the other triangle
12. type of triangle with 3 different lengths of sides
13. theorem stating that a line joining two midpoint of a triangle is parallel to the third side and is half of it
14. type of triangle where all angles are <90

1. type of triangle with 3 equal sides
3. type of triangle with 2 equal sides
4. type of triangle where one angle is 90
5. type of triangle where one angle is >90
7. congruence theorem stating that if the three sides of one triangle are equal to the corresponding three sides (SSS) of the other triangle, then the two triangles are congruent
8. congruence theorem stating that if the hypotenuse and side of one right-angled triangle are equal to the hypotenuse and the corresponding side of another right-angled triangle, the two triangles are congruent.
11. the perpendicular drawn from the vertex of the triangle to the opposite side
14. congruence theorem stating that two triangles are said to be congruent if two angles and the included side of one triangle are equal to two angles and the included side of another triangle
