Because they comply with the formula for any polygon which is:
(number of sides-2)*180 = sum of interior angles
A triangle has 3 sides so: (3-2)*180 = 180 degrees

What is true about the angles and sides on similar triangles?
All the Angles and sides on Triangles are always going to equal 180 Degrees
Do all triangles have an acute angle?
All triangles have at least 2 acute angles. All 3 angles of a triangle will equal 180 degrees.
What generalization can you make about all triangles?
all inner angles are equal to 180 degrees
Does an equallaterail triangle equal 360 degrees?
No. The sum of the angles in ALL triangles is equal to 180 degrees. No triangle's angles equal 360.
Do all triangles equals 180?
A triangle doesn't equal 180, but the sum of the internal angles of every triangle equals 180 degrees.

No. The sum of the angles in ALL triangles is equal to 180 degrees. No triangle's angles equal 360.
What is the measure of each of the interior angles of an equilateral triangle?
60 degrees. All the angles add up to 180. Equilateral triangles have all sides equal, and therefore all angles equal. 180/3 = 60.
Do all triangles equals 180?
A triangle doesn't equal 180, but the sum of the internal angles of every triangle equals 180 degrees.
Do all triangles have the same sum of their angles?
Yes, all triangles have the sum of their angles as 180 degrees.
Can an equilateral have one 75 degree angle?
No because a triangles inner angles must equal a whole 180 degrees and an equilateral has to have all equal interior angles and 75+75+75 does not equal 180
Are all triangles equal to 180 degrees?
Yes the 3 interior angles of any triangle add up to 180 degrees
Explain why a right triangle does not have three right angles?
All triangles have 3 angles that add up to 180 degrees. 90+90+90 does not equal 180.
Does and isocolies triangle equal 180 degrees?
Assuming the question was if an isosceles triangle have angles that add up to 180 degrees, then yes. All triangles have angles that add up to 180 degrees.
Are the sum of interior angles equal to 180 in right triangles only?
No. That's a good number for ALL triangles,no matter what their shape or size may be.
