90 degree triangles are always similar.
it is a series of isosceles triangles with all 90 degree angles and consist of 17 triangles
Acute triangles have angles less than 90 degrees. Right triangles have 90 degree angles.
All right angle triangles have a 90 degree angle and two acute angles that add up to 90 degrees
No, not all triangles have a 90 degree angle, so not all are perpendicular.
No, only right angle triangles, but all the angles in a triangle will add up to 180 degrees.
No. A triangle may have a 90-degree angle, but not all triangles do. The only requirement for being called a triangle is that it is a closed figure with 3 sides.No. A triangle may have a 90-degree angle, but not all triangles do.

Yes as well as a 90 degree angle
All triangles have 180 degrees.
triangles squares rectangles i think most shapes could have a 90 degree angle except a circle
It does not; if there is no 90 degree angle there is no hypotenuse.
If one corner is right, the other corners are together 90 degrees. So they're both still variable. So: no not all right triangles are similar
