GEOMETRY IS EVERYWHERE

TRIANGLES

• Triangles are three sided polygons whose angles add up to 180 degrees

DISTANCE

• Distance is a numerical description of how far apart objects are.

ACUTE ANGLE

• An angle less than 90 degrees

PARALLELOGRAM

• A 4 sided rectilinear polygon with opposite sides parallel

MIDPOINT

• The middle point of a line segment

RECTANGLE

• A rectangle is any quadrilateral with four right angles

SQUARE

• A polygon with four equal sides and four right angles

SEGMENT

• A part of a line that is bounded by two distinct end points

PARALLEL PLANES

• Two planes that do not intersect

SKEW LINES

• Two lines that don't intersect and are not parallel

EQUILATERAL TRIANGLE

• An equilateral triangle is a triangle with 3 equal sides

ISOSCELES TRIANGLE

• A triangle with two congruent sides

SCALENE TRIANGLE

• A triangle with three unequal sides

RIGHT TRIANGLE

• A triangle with one 90 degree angle

STRAIGHT ANGLE

• An angle of 180 degrees

VERTICAL ANGLES

• A pair of non-adjacent angles for when two lines intersect

COLLINEAR POINTS

• Points that lie on the same plane

CORRESPONDING ANGLES

• Two adjacent angles that that add up to 180 degrees

RIGHT ANGLE

• A 90 degree angle

PERPENDICULAR LINES

• Two lines that intersect to make four 90 degree angles
