Question

If a triangle is not a right triangle, then it does not have a 90o angle.t or f?

Answer 1

The statement that a triangle that does not have a 90° angle is not a right triangle is true. Triangles without a 90° angle can be either acute or obtuse.

Step-by-step explanation:

The statement is True. In basic geometric terms, a triangle is classified as a right triangle if it has an angle of 90°. If a triangle does not have an angle of 90°, it would not be a right triangle and can be either an obtuse triangle (one angle greater than 90°) or an acute triangle (all angles less than 90°).

1. Right Triangle: A right triangle is a type of triangle that has one angle exactly equal to 90°.
2. Acute Triangle: An acute triangle is a type of triangle in which all three angles are less than 90°.
3. Obtuse Triangle: An obtuse triangle is a type of triangle in which one angle is greater than 90°.

Note that the sum of all angles in a triangle is always 180°, irrespective of the type of triangle.
