Front

What is the Pythagorean theorem?

Back

In a right triangle, a² + b² = c², where c is the hypotenuse.

Front

What does it mean for two triangles to be similar?

Back

Two triangles are similar if their corresponding angles are equal and their sides are in proportion.

Front

How do you find the length of a side in a right triangle using trigonometric ratios?

Back

Use sine, cosine, or tangent based on the given angle and known side.

Front

What is the sine ratio in a right triangle?

Back

Sine = opposite side / hypotenuse.
