Front

What is the formula to find the length of a missing side in a right triangle?

Back

Use the Pythagorean theorem: a² + b² = c², where c is the hypotenuse.

Front

What does it mean to measure an angle to the nearest 10 degrees?

Back

Round the angle measurement to the closest multiple of 10.

Front

If one angle is 30° and another is 150°, what type of angles are they?

Back

They are supplementary angles because they add up to 180°.

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect; they are always equal.

Front

How do you find the length of a side in a triangle using the given angles?

Back

Use trigonometric ratios (sine, cosine, tangent) based on the known angles.

Front

What is the difference between complementary and supplementary angles?

Back

Complementary angles add up to 90°, while supplementary angles add up to 180°.

Front

What is the measure of a right angle?

Back

A right angle measures 90°.

Front

If two angles are adjacent, what does that mean?

Back

Adjacent angles share a common side and vertex but do not overlap.

Front

What is the sum of the interior angles of a triangle?

Back

The sum of the interior angles of a triangle is always 180°.

Front

How do you convert degrees to radians?

Back

Multiply the degree measure by π/180.
