Measure the angle to the nearest degree

Big Idea: A protractor measures the circular arc of an angle in units called degrees. This lesson focuses on measuring angles in whole number degrees. Students practice first estimating, then using the protractor while discovering the attributes of various angles.

The practice offered in this lesson will prepare students for . To the nearest degree , the measure of ZA is 2°.

Here you will be shown how to measure the size of any angle.

Place the centre of the protractor on the corner of the angle.

Answer (round to nearest degree ): X = sinX. Measuring , calculating and drawing angles. Find the measure of angle α, to the nearest degree.

A puzzle to help students to practise measuring angles to the nearest degree. An accompanying worksheet is attached. It would be kind of hard to measure since it would be so big to manipulate. Not to be confused with augly angles :) Watch th.

Fin correct to the nearest degree , the three angles of the triangle with the vertices A(3), B(5), C(--0). Solution: First using the triangle find the vector representations of the three lines. You are not given an angle measure , but you can use the definition of cotangent to find the value of n. Use the ratio you are given on the left side and the information from the triangle on the right side.

Cross-multiply and solve for n. Make sure your calculator is in degree mode! It seems reasonable to figure out there most be some algebraic way to determine the angle from the proportions and vice versa. Choose the estimate closest to what you think the angle is :–. Name each angle here (letters). Estimate its size (in your head).

Measure the angle to the nearest degree using your . I want to find the measure of the acute angle that they form because they form two . Your calculator screen should read when you press ENTER. Name___________________________________. Using Trigonometry to Find Angle Measures. Find each angle measure to the nearest degree.

Assume that lines which appear to be. SOLUTION: Slove each right triangle. Triangles made with radii are isosceles.

Round measures of side to the nearest tenth and measures of angles to the nearest degree.
