What is the thirty degree sixty and degree right triangle theorem?
If the triangle has a 30 degree angle and a 60 degree angle then the 3rd angle must be a 90 degree angle because there are 180 degrees in a triangle and so therefore it is a right angle triangle.
What kind of triangle has one 30 degree angle and one 60 degree angle?
A right triangle because all triangles equal 180 degrees. 180-60=120 120-30=90
Is it true if a triangle has a 60 degree angle its an equilateral triangle?
No. One isn't enough. It must have two of them.
What is a triangle that has two 60 degree angles?
It is an equilateral triangle because its 3rd angle has to be 60 degrees
What tringle has two 60 degree angle?
An equilateral triangle has two 60 degree angles which must make its third angle also 60 degrees

What kind of triangle has one 30 degree angle and one 60 degree angle?
A right triangle because all triangles equal 180 degrees. 180-60=120 120-30=90
Triangle with a perimeter of 9 and a angle of 60 with a similar triangle with a perimeter of 12 what is the angle degree of the second triangle?
== == The corresponding angle is 60 degrees.
Is it true if a triangle has a 60 degree angle its an equilateral triangle?
No. One isn't enough. It must have two of them.
What is 30-60-90 right triangle?
A 30-60-90 right triangle is one in which the three angles of the triangle 30, 60 and 90 degrees. The length of the sides of such a triangle have the ratio 1:2:square root of 3. The 1 is opposite the 30 degree angle, the 2 is opposite the 60 degree angle and the square root of 3 is opposite the 90 degree angle.
What is a triangle that has two 60 degree angles?
It is an equilateral triangle because its 3rd angle has to be 60 degrees
What tringle has two 60 degree angle?
An equilateral triangle has two 60 degree angles which must make its third angle also 60 degrees
Tyler draws a triangle with a 35 degree angle and a 85 degree angle what is the measure of the third angle?
a triangle has 180 degrees 35+85=120 180-120=60 the third side is 60 degrees
What is an angle called that is 60?
Acute. A 60-degree angle is also called a 'special triangle angle' since it appears in the special triangle 1, root(3), 2
If angle A in a triangle is 60 degrees and angle B is 20 degrees what is the degree of angle C?
100
Show how to construct a 120 degree angle?
draw a base and use this to draw an equilateral triangle each angle of an equilateral triangle adds up to 60 degrees. To have an angle of 120 degree use this angle and then draw another side of a triangle next to it to get a 120 degree angle.
Is an equilateral triangle have a acute angle in it?
An equilateral triangle has three acute (60 degree) angles.
