Let's practice making triangles and start thinking about when it's possible or impossible to make a triangle.
Area_and_circumference_challenge_problems
Problems that stretch your understanding of area and circumference of circles
Learn to find volume of rings, triangular prisms, and rectangular prisms inside of other rectangular prisms.
Vertical_complementary_and_supplementary_angles
Learn three types of angle pairs: vertical angles, complementary angles, and supplementary angles.
Area_and_circumference_of_circles
A circle is at the foundation of geometry, and at the foundation of a circle is a special number called Pi. This number allows us to relate the radius, diameter, and circumference of a circle.
When we slice (cut through) a 3D shape, we make a 2D shape called a cross section. In this tutorial, we think about the different cross sections we can make by slicing 3D shapes.
Practice finding missing angles in figures using your knowledge of vertical, supplementary, and complementary angles.
A map depicts objects much smaller than they are in real life. A map is a great example of a scale drawing. In this tutorial, we'll take a mathematical look at the nature of scale drawings.
