Background Tutorials

  • Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.

      What are Acute, Obtuse, Right, and Straight Angles?

      Did you know that there are different kinds of angles? Knowing how to identify these angles is an important part of solving many problems involving angles. Check out this tutorial and learn about the different kinds of angles!

  • Understand that a two-dimensional figure is congruent to another if the second can be obtained from the first by a sequence of rotations, reflections, and translations; given two congruent figures, describe a sequence that exhibits the congruence between them.

      What Does Congruent Mean?

      If two figures have the same size and shape, then they are congruent. The term congruent is often used to describe figures like this. In this tutorial, take a look at the term congruent!

Further Exploration

  • Use facts about supplementary, complementary, vertical, and adjacent angles in a multi-step problem to write and solve simple equations for an unknown angle in a figure.

      How Do You Use Complementary Angles to Find a Missing Angle?

      If two angles are complementary, that means that they add up to 90 degrees. This is very useful knowledge if you have a figure with complementary angles and you know the measurement of one of those angles. In this tutorial, see how to use what you know about complementary angles to find a missing angle measurement!
