Pg.1
When two angles have the same measure, they are Congruent Angles Pg.2
Vertical Angles are the angles opposite each other when two lines cross Pg. 3
Two lines are perpendicular if the product of their slopes is -1. Also, the two intersecting lines form right angles. Pg.3
Two or more lines that meet at a point are called intersecting lines. That point would be on each of these lines. In Figure 1, lines l and m intersect at Q.1 Pg.4
Two Angles are Supplementary if they add up to 180 degrees. Pg.5
The relation or adaptation of one portion to another, or to the whole, as respect magnitude, quantity, or degree; comparative relation; ratio; as, the proportion of the parts of a building, or of the body. Pg. 7
A point can be imagined as an infinitely small dot, a line resembles a tough string that is being stretched. A line is a straight line.
Length is a measurement of distance or dimension. A Segment is a portion cut off from a geometric figure by one or more points, lines, or planes
A Ray is a line which starts at a point with given coordinates, and goes off in a particular direction to infinity, possibly through a second point.linepointcoordinates A Postulate is a statement accepted as true without proof. A postulate should be so simple and direct that it seems to be unquestionably true.
Two rays sharing a common endpoint. Angles are typically measured in degrees or radians.raysmeasured degreesradians A Protractor is a circular or semicircular tool for measuring an angle or a circle.
A Acute Angle is an angle that has measure less than 90°.angle measure A Obtuse Angle is an angle that has measure more than 90° and less than 180°.angle
A Right Angle is a 90 ° angle. angle A Straight Angle is a 180° angle.angle
Bisector is a line segment, line, or plane that divides a geometric figure into two congruent halves.line segmentlineplanegeometric figure congruent Two acute angles that add up to 90°. For example, 40° and 50° are complementary.acute angles
