About This Worksheet
This easy-level worksheet contains 15 problems designed for 10th Grade students practicing solving right triangles. Easy worksheets use simpler numbers and straightforward problem types to build confidence and reinforce foundational skills.
Solving a right triangle — finding every side and every angle — is a fundamental skill in surveying, navigation, architecture, and physics. The ability to move fluently between sides and angles using trig functions gives students a complete toolkit for working with any right triangle in any applied context.
- Find all missing side lengths using sine, cosine, and tangent
- Find all missing angle measures using inverse trig functions
- Apply the Pythagorean Theorem alongside trig ratios in complete right triangle problems
- Solve right triangles embedded in geometric figures like hexagons and circles
- Verify solutions by checking that all angles sum to 180 degrees
How to Solve: Worked Example
- The three angles sum to 180°, and one is exactly 90°.
- So the two acute angles sum to 90°.
- 90 - 47 = 43°.
