Identify Properties of Right Triangles

This lesson covers the unique properties of right triangles, including having one right angle, two legs, and one hypotenuse. It explains that the size and orientation of right triangles do not define them, and emphasizes the importance of identifying the right angle to determine the legs and hypotenuse. The lesson also highlights the special relationship between the side lengths of right triangles, which will be explored further in subsequent lessons. By understanding these properties, students can easily identify right triangles.

What distinguishes a right triangle from other types of triangles?

• It has no angles.

• It has three equal sides.

• It has a right angle.

• It has four sides.

Which side of a right triangle is always opposite the right angle?

• Base

• Hypotenuse

• Leg 2

• Leg 1

How many legs does a right triangle have?

• One

• Three

• Two

• Four

What is true about the orientation of right triangles?

• They must be vertical.

• They must be horizontal.

• They can be of any orientation.

• They must be upright.

• The color of triangles

• The special relationship between side lengths

• The angles of a square

• The number of triangles in a polygon
