Acute angle and Adjacent angles and Axis

• Acute angle are angles that are less than 90• Two angles are Adjacent if they have a

common side and a common vertex and don't overlap.

• A Axis is the horizontal and vertical lines where the scale is on an graph.

Bisecting an angle and Concentric circles and Congruent figures

• To bisect an angle means that you divide the angle into two equal parts without actually measuring the angle.

• Concentric circles are circles that have the same center.

• Congruent figures are figures that have the same size and shape.

Consecutive sides and Corresponding angles and Inscribed

• Consecutive sides is a angle with two angles in a polygon that share a common side.

• Corresponding angles are angles that when two lines are crossed by another line the angles in opposite. corners are called corresponding angles.

• An Inscribed figure is a figure that is drawn inside another, usually with the edges touching.

Isometry and Transformation and Line of reflection

• Isometry is the same shape, but in a different place.• Transformation means to flip, slide or turn a shape.• Line of reflection is the exact middle of a shape that

is that same on each side of the line.

Mid point and Obtuse angle and Ordered number pair

• Midpoint is a dot that always separates the ends into half and half.

• Obtuse angle is a angle bigger than 90, but smaller than 180.

• Ordered number pair is two numbers written in a certain pattern.

Parallel line and Perpendicular and Perpendicular bisector

• Parallel line is a line that is even with another line and they never touch.

• Perpendicular lines cross and when they touch the make a 90 degree angle.

• Perpendicular bisector is when two lines hit each other and create a right angle

Reflection and Reflex angle and Right angle

• Reflection is side you had projected on glass.• Reflex angle is a angle that is more than 180

and less 360.• Right angle is two lines that are crossed and

create a 90 degree angle.

Rotation and Sector and Straight angle

• Rotation is when you move a shape to a different orentation

• A Sector is a section of a pie circle.• Straight angle is exactly 180 degrees.

Supplementary angles and Transformation and Translation

• Supplementary angles have to add up to 180 degrees.

• Transformation is just moving a shape so it is in a different position.

• Translation is moving a shape without flipping it.

Transversal and Vertex and Vertical angles

• Transversal is a line that crosses at least two other lines.

• Vertex is the corner of a polygon• Vertical angles are opposite angles.
