Master geometry terms! Practice definitions and matching for angles, polygons, and triangles.

Vocabulary Match the vocabulary words with their definition. Line has no endpoints and extends indefinitely in both directions Complementary Angles are two angles whose sum measures 90 degrees. Supplementary Angles are two angles whose sum measures 180 degrees. Vertical Angles are two nonadjacent angles formed by 2 intersecting lines. They are equal in measure Adjacent Angles angles that share a common vertex and a common side. (next to each other) Alternate Interior Angles are two interior angles on opposite sides of the transversal. Corresponding Angles are one exterior and one interior angle are on the same side of the transversal Polygon a closed figure Triangle a 3 sided polygon Click on t he line and pick the Geometry Term that goes with the definition. 1) Acute Triangle - triangle that has three acute angles2) Obtuse Triangle - a triangle that contains one obtuse angle3) Right Triangle - a triangle that contains one right angle4) Equiangular Triangle - a triangle that has 3 congruent angles5) Scalene Triangle - a triangle with no congruent sides6) Isosceles Triangle - a triangle with 2 congruent sides and 2 congruent base angles7) Equilateral Triangle - a triangle with three congruent sides8) Altitude - a line that extends from a vertex of a triangle perpendicular to the opposite side9) Median - a line that extends from a vertex of a triangle to the midpointof the opposite side10) Linear Pair - two adjacent angles whose sum is a straight angle
