Do all equilateral triangle angles equal 180?
All sides are the same length (congruent) and all interior angles are the same size (congruent). To find the measure of the interior angles, we know that the sum of all the angles is 180 degrees (from above)… And there are three angles… So, the measure of the interior angle of an equilateral triangle is 60 degrees.
Are equilateral triangles 90 degrees?
Explanation: An equilateral triangle has all angles equal to 60 degrees. For a right triangle one angle has to be 90 degrees. Only if it’s a curvilinear triangle – e.g. on the surface of a sphere.
Are the angles of an equilateral triangle each 45 degrees?
If all three sides are the same length, then it is an equilateral triangle, and the three angles contained by those sides are the same. So an equilateral triangle is also an equiangular triangle. An important point to remember is that, in this case, all three angles measure 60 degrees.
Why is every angle 60o in an equilateral triangle?
An equilateral triangle is one in which all three sides are congruent. It also has the property that all three interior angles are equal. In other words, all three angles of an equilateral triangle are always 60°. Since all sides are congruent, the other two sides both measure 12 centimeters.
Can an equilateral triangle be a right angle?
No, a right triangle cannot be an equilateral triangle.
What triangle angle measures 90?
A triangle with one 90° angle is called a right triangle.
What angle measures 180 degrees?
straight angles
Angles that are 180 degrees (θ = 180°) are known as straight angles.
Is 60 degrees a right angle?
60 degree angle is an acute angle, as angles smaller than a right angle (less than 90°) are called acute angles. In the case of a geometric angle, the arc is centered at the vertex and constrained by the sides….60 Degree Angle.

What triangle is 60?
equilateral triangle
= 60 , an equilateral triangle will always have three 60° angles.
What is a 30 60 Triangle?
A 30-60-90 triangle is a special right triangle (a right triangle being any triangle that contains a 90 degree angle) that always has degree angles of 30 degrees, 60 degrees, and 90 degrees. The side opposite the 60° angle will be the middle length, because 60 degrees is the mid-sized degree angle in this triangle.
