Triangle means 3 angles. No other shape exists and any three angle shape is a triangle
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.
A shape that has one corner is a cone.
Many 3d shapes have a corner.
The corner of a triangle is a vertex.A vertex is defined as an angle is the endpoint where two line segments or lines come together. Every triangle has three vertices.
triangle
It will have an L shape flipped around at the corner. or you can use a protractor or type in google images 'right angle triangle' they will have an L shape at the corner of the right angled triangle.
Vertex Plural: Vertecies

A quarter of a whole circle or half a semicircle
rectangle is the "special name" of a shape with 4 corners (square). triangles are split in 3 groups. right triangle, one corner is 90 degrees equilateral triangle, every corner is 60 degrees isosceles triangle, two sides have the same length
To make a square with paper, fold one corner of the paper diagonally to the opposite corner, creating a triangle. Then, fold the two outer corners of the triangle inwards towards the center, creating a square shape. Press down on the folds to secure the square shape.
To make a square out of paper, you can start by folding one corner of the paper diagonally to the opposite corner, creating a triangle. Then, fold the two outer corners of the triangle inwards towards the center, creating a square shape. Finally, unfold the paper to reveal the square shape.
Not true. A triangle with angles of 90, 45 and 45 is a right angled isosceles triangle. If you take a square piece of paper and fold it in half - from corner to corner - you will get this shape.
For a right angle triangle the square looking shape in the corner represents 90 degrees
Take a corner of the triangle and fold it over so that the corner is not over the rest of the triangle.
