The angles add up to 180 degrees, but the angles are 60 degrees.
270 degrees
They have three connecting lines. The three interior angles add up to 180 degrees. The three exterior angles add up to 360 degrees.
There are three angles in triangles, the measures of which total 180 degrees.
A triangle has three sides and three angles that total 180 degrees.
No. The sum of the three interior angles of a triangle will always be 180 degrees.
The sum of the interior angles of a quadrilateral is 360 degrees. If three of the angles are right angles, that is, of 90 degrees each, the the fourth must be 90 degrees. So you can have a quadrilateral with three right angles but its fourth angle will also be a right angle. So exactly 3 right angles is not possible.
Triangle is plane with three sides and three angles. The sum of its inside angles is equal to 180 degrees.
