Question

4 a triangle with an angle equal to 110 degrees is known as which of the following? isosceles triangle, right angle, acute triangle, obtuse triangle. skip 3/10 complete

Explanation:

To determine the type of triangle with a 110 - degree angle, we analyze each option:

• Isosceles triangle: Defined by having at least two equal - length sides (or two equal angles), not by a specific angle measure like 110 degrees. So this is not the correct classification based on the 110 - degree angle.
• Right angle triangle: Has one angle equal to 90 degrees. Since 110≠90, this option is incorrect.
• Acute triangle: All angles in an acute triangle are less than 90 degrees. But 110>90, so this is not an acute triangle.
• Obtuse triangle: A triangle with one angle greater than 90 degrees (and less than 180 degrees) is an obtuse triangle. Since 110>90, a triangle with a 110 - degree angle is an obtuse triangle.

Answer:

D. Obtuse Triangle
