Types of Angles
Angles are formed by putting together two of these two geometry figures.
What are rays?
This geometry term describes a dot that is named by a capital letter.
What is a point?
This type of triangle has three equal sides.
What is an equilateral triangle?
This angle in a circle creates two 180 degree angles.
What is a straight angle?
These are the three dimensions of a rectangular prism.
What are length, width, and height?
This is the place that the center of your protractor should line up with to measure an angle.
What is the vertex?
This geometry term is a straight path that goes on forever in both directions.
What is a line?
This type of triangle has one angle that is 90 degrees.
What is a right triangle?
This is the distance from the center to the outside of a circle.
What is the radius?
This term refers to how much space is inside a 3D shape
What is volume?
This type of angle is greater than 90 degrees.
What is an obtuse angle?
This geometry term is part of a line that has two ends.
What is a line segment?
This type of triangle has no equal sides
What is a scalene triangle?
This is a line that touches only one point on the outside of a circle
What is a tangent line?
This term could be used to describe how much paper you'd need to completely cover the faces of a 3D shape.
What is surface area?
This type of angle is exactly 90 degrees.
What is a right angle?
This geometry term is formed by two rays with the same endpoint.
What is an angle?
This type of triangle has two equal sides.
What is an isosceles triangle?
What is 360 degrees?
This shape is formed by rotating a triangle around a central axis.
What is a cone?
When naming an angle, the answer should include these elements.
What are the letters of the angle with the vertex in the middle? (ie. angle DEF)
This geometry term is the total length of all sides of a shape.
What is the perimeter?
This is the sum of all the angles in a triangle.
What is 180 degrees?
This type of angle in a circle is greater than 180 degrees.
What is a reflex angle?
This figure has five faces, four of which are triangle and one of which is a square.
What is a square pyramid?
