Is it possible to make a triangle with 2 right angles?

No you cannot make a triangle with two right angles. In all triangles the sum of the angles is always 180°. Also all triangles have three angles. If there are two right angles, you already have 180° and cannot have another angle to complete the triangle.


How many triangle doese it take to make a rhombus?

2 triangles make up a rhombus which has 4 interior angles adding to 360 degrees and a triangles has 3 interior angles add up to 180 degrees. Therefore: 360/180 = 2 triangles


Are all the triangles similar?

No because there are different types of triangles but they all have 3 sides and 3 inside angles that add up to 180 degrees


What generalization can you make about all triangles?

all inner angles are equal to 180 degrees


What are sides of a triangle?

All triangles have 3 sides and 3 inside angles that add up to 180 degrees


Do all triangles have the same sum of their angles?

Yes, all triangles have the sum of their angles as 180 degrees.


How do the angles inside a quadrilateral add up to 360?

If you cut any quadrilateral along one of its diagonals, the figures formed are two triangles. Since the sum of the angles of a triangle is 180 degrees, then the sum of the angles of two triangles is 2(180) = 360 degrees. For this reason, the sum of the angles of a quadrilateral is 360 degrees.


How many sides can a triangle have?

All triangles have 3 sides and 3 inside angles that add up to 180 degrees


What do the angles add upto on a 5 sided shape?

Assume each side is a straight line segment. With 3 sides you can make 1 triangle with a sum of interior angles = 180°. With 4 sides you can make 2 triangles with a sum of interior angles = 2 x 180° = 360°. With 5 sides you can make 3 triangles with a sum of interior angles = 3 x 180° = 540°.


What is the sum of the interior angles of any triangles?

180


What are the properties of isosceles triangles and an equilateral?

180 ANGLES


What do the angles of a five sided polygon add up to?

540 degrees. you figure it out by seeing how many triangles you can make in the polygon (without crossing lines), and, because triangles equal 180 degrees, you multiply 180 times how many triangles you can make.
