Two. Two acute angles in a right triangle.
Yes a 90- 60-30 triangle for example because there are 180 degrees in a triangle.
Such a triangle would presumably have one right angle, and two acute angles. A right angle has a measure of 90 degrees; an acute angle has a measure of less than 90 degrees. Since both of the other two angles in a right triangle must be acute angles, you'd think at first that every right triangle must be a right acute triangle. But when you go and look up the definition of an "acute triangle", it turns out to be a triangle in which all three angles are acute. So the fact is that there's no such thing as a right acute triangle, because the 90-degree angle in a right triangle is not acute.
A triangle cannot have two right angles. Triangles angles should add up to 180. There are three angles. If there are 2 right angles, there would be no third angle, therefore, no triangle. XD
isosceles triangle
Yes in a 90 45 45 triangle
No. The two acute angles in a right triangle must add up to 90 degrees. The two you have listed don't.
...a right 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°.
They have one 90 degree angle and two 45 degree angles
There are three angles in a triangle but to measure them you would use a protractor.
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.
Use the pythagorean theorem.
Yes
Right angles are 90°. The total measure of a triangle is 180°. So, the sum of the other two angles must equal 90°.
An isosceles triangle has two equal angles.
The sum of two complementary angles is 90 degrees. The three angles of a triangle add up to 180 degrees. Hence, if you subtract the complementary angles from 180, you have the measure of the third angle: 180 - 90 = 90 (this is the third angle) As a rule, if two angles of a triangle are complementary, the third angle is a right angle (90 deg). The three angles together form a right triangle.
