Square.
a lot of shapes do if you think about it. a triangle(right triangle) A square and rectangles
that is a square with a triangle inside turned
For a right angle triangle the square looking shape in the corner represents 90 degrees
A triangle Square An equilateral triangle on a sphere that distends 90 degrees (think of a triangle with one corner at the north pole, one corner on the equator at the 0 meridian, and one corner on the equator at 90 degrees longitude. Each corner of this spherical triangle measures 90 degrees.
every triangle has 180 degrees, irrespective of its shape.
A right angle triangle. (if it is a triangle)
triangle
a triangle.
A hexagon or pentagon will have obtuse angles (greater than 90 degrees). A triangle has angles that are all less than 90 and a square has only 90.
A square and a rectangle have each of their angles as 90°. However, no polygon or shape (unless it is not closed) can have a total angle sum of 90°
every triangle no matter the shape has a total of 180 degrees. more specifically an equilateral triangle has three degrees each measuring 60 degrees.
