Two. Two acute angles in a right triangle.
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
A triangle with two 45 degree angles must be a right triangle.
The two other angles are 45 degrees each. The three angles of every triangle always add up to 180 degrees. -- A right triangle is a triangle that has a right angle in it. -- A right angle is 90 degrees. -- That leaves 90 degrees for the other two angles in the right triangle. -- If it happens to be isosceles, then the other two angles are equal. -- Those must both be 45 degrees.
no only a right triangle can have1 right angle not 2!!
A triangle with one right angle and two acute angles is called a right triangle. In a right triangle, one of the angles measures 90 degrees, making it a right angle, while the other two angles are acute, meaning they measure less than 90 degrees each. The Pythagorean theorem can be applied to solve for the lengths of the sides of a right triangle.
A right angled triangle can only have two acute angles.
There are no obtuse angles in a right triangle. A right triangle consists of one right angle and two acute angles.
An obtuse triangle can have no right angles, and has two equal angles.
Two. Two acute angles in a right triangle.
It is impossible to have a triangle with two right angles. This is because a triangle=180 degrees. Two right angles would make up all of the 180 degrees.
In a right angled triangle the two other angles are acute.
In a right angled triangle the two other angles are acute.
No, because two right angles=180 degrees. A triangle has three sides and is 180 degrees, so two right angles would not form a triangle.
If a triangle is an isosceles triangle as well as being a right-angled triangle, the size of the two angles (that are not right angles) are 45 degrees.
No, not with two right angles. All the angles in a triangle add up to 180, you have that in two angles.
Yes. A right triangle is a triangle where one angle is a right angle. If two out of three angles are right angles, then it's an isosceles triangle. If all three angles are right angles, then it is an equilateral triangle.
