• Points
• A point is precise location in space. It is labeled with a letter.
• Intersecting
• Crosses at a point
• Parallel
• Lines that never cross and are in the same plane.
• Perpendicular
• Intersects at right angles 90 degrees.
• Skew Lines
• Lines that are not in the same plane.
• Types of Angles
• Right angle
• Obtuse angle
• Acute angle
• Vertex/Vertices

• Right Angle
• Exactly 90 degrees
• Acute Angle
• Less than 90 degrees
• Obtuse Angle
• More than 90 degrees
• Types of Triangles Right Obtuse Acute Scalene Isosceles Equilateral
• Right Triangle A right triangle is a triangle with one side that is 90 degrees.
• Acute Triangle An acute triangle is a triangle with the biggest side that is less than 90 degrees.
• Obtuse Triangle An obtuse triangle is a triangle that the biggest angle is bigger than 90 degrees.
• Scalene Triangle A triangle that has all different sides.
• Isosceles Two sides on a triangles that are the same.
• Equilateral A triangle that all angles are the same.
• Quadrilateral A type of shape with 4 angles.
• Trapezoid A shape with 1 set of parallel lines.
• Parallelogram A shape that has all sides parallel.

• Circles Chords Diameter Arc Radius Sector Circumference
• Chords A straight line between two points of a curve.
• Diameter A straight line the travels through the middle of a circle.
• Arc A continuous section in a circle.
• Radius A straight line that travels half of the circle.
• Sector A piece of a circle.
• Circumference The length of a circle. 98
