Any triangle that has an angle measuring 90 degrees is a right triangle.
It is a right angle triangle and its 3rd angle is 70 degrees.
It is a right angle triangle and the 3rd angle will measure 30 degrees
It is a right angle triangle providing that the 3rd angle is 30 degrees.
An isosceles triangle, because the angles of a triangle add up to 180 and you already know that one angle measures 120 degrees, the other is 30, and so the unknown angle must also be 30 degrees. Since two of the angles are the same, two of the sides are going to be the same, making it an isosceles triangle.
A right angle triangle and the third angle measures 60 degrees
A triangle with the third angle that measures 30 degrees.This triangle is not isosceles nor equilateral but has one obtuse angle.
right triangle and the other angle would be 70 degrees. Hope I helped :)
A right triangle is a triangle in which one angle is equal to 90 degrees and the remaing two angles are acute(ie., less than 90 degree). so this triangle is a right angle triangle.
