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 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 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
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.
"Vertex" is the plane-geometry term for a corner, so a triangle has three, a square (or any other four-sided shape) has four, a pentagon has five, and so on.
If the room is of square or rectangular shape then the diagonal is the shortest path it can choose to walk on. If the room is of triangular shape then it can walk along the side of the triangle to reach the opposite corner.
