Real-life objects
Real-life objects represent a point, line, ray, line segment or a plane. Location on a Map
Point
Angles A and B are supplementary angles. If m∠A is three-fourths m∠B, what is m∠A?
77.14 degrees
The point at which a segment is divided into two congruent segments.
Midpoint
True or False: We can also use counting units (like grid squares) to estimate or determine the area or perimeter of a given polygon.
True
Find the Midpoint: (3, -5) and (4, 1).
(3.5, -2)
Real-life objects represent a point, line, ray, line segment or a plane. Tabletop
Plane
Two angles are complementary. m∠BDC = x+8 and m∠CDA = 2x-8. Find m∠BDC.
38 degrees
Give an undefined term in Geometry.
Point, Line, Plane
A polygon with vertices A (5, 0), B (5, 3), and C (0, 0). Find the perimeter.
13.83 units
Find the Distance: (-6, -7) and (5, -2).

Real-life objects represent a point, line, ray, line segment or a plane. Laser point
Ray
Two angles are complementary. m∠BDC = x+8 and m∠CDA = 2x-8. Find m∠CDA.
52 degrees
Two angles that share a common vertex and a common side but do not overlap.
Adjacent Angles
A polygon with vertices L (–3, –4), O (–3, 1), V (5, 1), and E (5, –4). Find the perimeter.
26 units

(3.5, 1)
Real-life objects represent a point, line, ray, line segment or a plane. Highway
Line
True or False: If line segment AB bisects line segment CD at point E, then CE + ED = AD.
True
A fundamental statement or assumption in geometry that is accepted as true without proof.
Postulate
A polygon with vertices A (5, 0), B (5, 3), and C (0, 0). Find the area.
7.5 units
Find the Distance: (-1, -2) and (-3, -4)
= 2.83 units
Real-life objects represent a point, line, ray, line segment or a plane. Ruler
Line Segment
True or False: If line segment AB bisects line segment CD at point E, then D is the midpoint of line segment AB.
False
Is a figure formed by two rays (sides of the angle) that share a common endpoint (or vertex).
Angle
A polygon with vertices L (–3, –4), O (–3, 1), V (5, 1), and E (5, –4). Find the area.
40 units
