Question

Geometry help needed

Answer 1

An acute angle is an angle that is smaller than 90 degrees,

An obtuse angle is an angle that is larger than 90 degrees,

A right angle is an angle that is 90 degrees,

And a straight angle is an angle that is 180 degrees.

4. 14 < 90, 14 ≠ 180 so acute

5. 114 > 90, 114 ≠ 180 so obtuse

6. 90 = 90 so right

7. 139 > 90, 139 ≠ 180 so obtuse

8. 179 > 90, 179 ≠ 180 so obtuse

9. 73 < 90, 73 ≠ 180 so acute

Answer 2

• Acute: less than 90 degrees
• Right: equal to 90 degrees
• Obtuse: greater than 90 degrees
• Straight: equal to 180 degrees

4. m∠LGH = 14 ---acute

5. m∠SRT = 114 ---obtuse

6. m∠SLI = 90 ---right

7. m∠1 = 139 ---obtuse

8. m∠L = 179 ---obtuse

m∠P = 73 ---acute
