Respuesta :
- 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
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
