It is a right angle triangle because it has a 90 degree angle and the 3 angles add up to 180 degrees.
an equiangular triangle meaning all the angles are equal or congruent measures
Equilateral triangle, regular triangle.
Like this: /\ / \ <-- triangle /__\ / /\ /__ /_\ <-- another triangle /\ | | Parallelogram
A congruent triangle is one where all the angles are identical to those of another triangle, or equivalently, all three sides are the same ratio to the sides of another triangle.
Answer: Another Triangle
an equiangular triangle meaning all the angles are equal or congruent measures
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.
Equilateral triangle, regular triangle.
An equilateral triangle can also be called a "regular" triangle
Like this: /\ / \ <-- triangle /__\ / /\ /__ /_\ <-- another triangle /\ | | Parallelogram
right triangle
An isosceles triangle.
77 degrees
77. The sum of the three angles in a triangle equal the sum of 180 degrees
Altitude is another word for a height of a triangle.
A congruent triangle is one where all the angles are identical to those of another triangle, or equivalently, all three sides are the same ratio to the sides of another triangle.
