Triangles and their properties
Angle: Measure of turn
Congruent Triangles: Triangles that are identical to each other in both side lengths and angle measurements
Equilateral Triangle: A triangle that has all 3 sides with equal lengths and angle measurements (60 degrees)
Isosceles Triangle: A triangle that has two sides with equal lengths. The angles opposite the two sides have equal angle measurements
Similar Triangles: Triangles that are identical to each other in angle measurements only. The triangles are proportional to each other in side lengths
Vertical angles: Opposite angles formed from the intersection of two lines that must have identical angle measurements
