Geometric Foundations

An angle with measure equal to 90°

• Acute angle

• Complementary angle

• Straight angle

• Right angle

• Straight angle

• Supplementary angle

• Linear pair

• Obtuse angle

The point where two rays, segments, etc. come together

• Midpoint

• Ray

• Vertex

• Intersection

Two angles that share a common vertex and side, but have no common interior points

• Supplementary angles

• Complementary angles

• Adjacent angles

• Vertical angles

A ray or segment that divides something into two parts that are congruent

• Bisector

• Vertex

• Midpoint

• Intersection

Points that lie on the same line
