GUARANTEED TO PASS.
Interest. Answer: Formula: interest= principal x rate x time (I=
PxRxT)
Point. Answer: -A point has no dimension
-It is represented by a dot
-A point is written using an upper-case letter
Line. Answer: -A line has one dimension
-Named using any two point on a line w a two sided arrow above them
-It can also be named using a lower-case cursive letter
Collinear Points. Answer: Points that are on the same line
Plane. Answer: -A plane has two dimensions
-It is represented by a shape that looks like a floor or a wall, but it
extends w/o an end
,-Through any three points not on the same line there is exactly one plane
-A plane is written using 3 non-collinear points or with upper-case
cursive letter
Coplanar points. Answer: Points that lie in the same plane
Line Segment. Answer: A line segment is named using both end
points with a line above them
Ray. Answer: A ray is named using its endpoint first and then any
other point on the ray pointing to the right above them
Intersecting lines. Answer: 2 lines that share exactly one point
Parallel lines. Answer: 2 lines that are always the same distance
apart and never touch
Perpendicular lines. Answer: The relationship between 2 lines which
meet at a right angle (90degrees). Perpendicular lines= 2 lines intersect
at a right angle
Right angle. Answer: 90 degrees
, Straight angle. Answer: 180 degrees
Acute angle. Answer: between 0 degrees and 90 degrees
Obtuse angle. Answer: between 90 degrees and 180 degrees
Complementary angles. Answer: 2 angles that have the sum of 90
degrees
Supplementary angles. Answer: 2 angles that have the sum of 180
degrees
the sum of the angle measures in a triangle. Answer: 180 degrees
