One angle of an isosceles triangle measures 100 degreas What are the measures of the other 2 angles?
The other two angles will be 40 degrees each.
How do you find the measures of the angles in a right isosceles 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.
Does a right angle triangle have 90?
A right triangle is a triangle in which one of the three angles measures 90°. In other words, it is a triangle with two sides that are perpendicular to each other.
Can an obtuse triangle have congruent angles?
Yes, an obtuse triangle can have two congruent angles, where for the obtuse angle measuring A degrees, each of the two other angles measures (180-A)/2.
How to Prove that a triangle cannot have two right angles?
The sum of the interior angles of a triangle is 180 degrees. If one angle is 90, that leaves 90 for the other two angles. You can't have another angle of 90 and an angle of 0, so there can only be one angle in a triangle that measures 90 degrees.
