How many sides does a triangle and a square have?
A square and a rectangle each have 4 sides and 4 angles. The only difference between them is that a square is a rectangle with equal sides. Both have 4 90 degree (right) angles. A triangle has 3 sides and 3 angles.
How many sides does triangle have?
3
Triangle/Number of edges
Every triangle has three sides and three angles, some of which may be the same. The sides of a triangle are given special names in the case of a right triangle, with the side opposite the right angle being termed the hypotenuse and the other two sides being known as the legs. All triangles are convex and bicentric.
What does a triangle and a square have in common?
Being a triangle is more like being a quadrilateral than it is like being a rectangle or a square. Children need to know that you can have lots of different side lengths and angles in a triangle, but if it’s a square then all of the sides have to have the same length, and all of the angles have to be right angles.
What shape is a triangle?
In geometry, a triangle is a closed, two-dimensional shape with three straight sides. A triangle is also a polygon.
Do triangles have 3 straight sides?
A triangle is a shape formed when three straight lines meet. All triangles have three sides and three corners (angles). The point where two sides of a triangle meet is called a vertex. The base of a triangle can be any one of its three sides, but it is usually the bottom one.
Which shape has 3 more sides than a triangle?
Polygons: How Many Sides?

| 8 | octagon |
| 9 | nonagon, enneagon |
| 10 | decagon |
How many sides does a triangle have inside?
A triangle has 6 sides, there are 3 straight edges in AND out side of a triangle. I am fairly sure that a triangle has 12 sides (3 insides and 3 outsides on each side).
Are there any shapes that have three sides?
The shapes listed in this article are all polygons. Triangles have three sides. The triangle is a very distinctive shape, only ever consisting of three sides connected together. If you ever see a shape that has three sides, it cannot be anything else but a triangle.
How many sides does a three sided polygon have?
Triangle is a polygon. Three sided polygon is a triangle. A triangle has three sides (edges), angles, vertices (corners), medians, altitudes, perpendicular bisectors, angular bisectors.
Which is the correct way to group triangles?
Every triangle is either an acute triangle, an obtuse triangle, or a right triangle. Another way to group triangles is by looking at the lengths of their sides: Equilateral triangle: An equilateral triangle is one in which all three sides have the same length.
