angles that measure 90 degrees.
90 degrees
If it has no right angles, it is not a right triangle and therefore you cannot name a hypotenuse of that triangle. Which implies you cannot find that side's measure.
Is a right angled triangle.
A Triangle which do not have a right angle.
An acute triangle.
No.
Yes in a 90 45 45 triangle
A right triangle. Also an isosceles triangle.
If you mean angles then it is a right angle triangle or an isosceles right angle triangle
Since the sum of the measures of the angles in a triangle is 180°, and a right angle has a measure of 90°, it follows that the other two angles together have a measure of 90°.
no. the angles in a triangle must add up to 180 degrees. The right triangles must have an right angle (90 degrees). If you add up all the angles they will not measure 180 degrees.
