there are 3 different types of triangles:
an equilateral triangle: all sides and angles are the same
an isosceles triange: 2 sides are the same and the 2 base angles are equal
a scalene triange: nothing is the same
If two angles and the side opposite one of them in one triangle are equal to one side and two similarly located angles in a second triangle then the two triangles are congruent. (The triangles are exactly the same shape and size as each other).
It means that if you take a piece of paper and cut out 8 little squares from it, with each square beingexactly 1 inch on a side, then the amount of paper in these 8 pieces will exactly cover the shape,no matter what shape the shape is.
A Right Triangle or sometimes called a Right-angled Triangle has one angle = 90 degrees
A triangle has three faces. In geometry, a face refers to a flat surface of a solid shape. Since a triangle is a two-dimensional shape with three sides, it has three faces. Each side of the triangle forms one of its three faces.
pentagonal square
Triangular means in the shape of a triangle: having three sides.
By definition, there is no such thing as a triangle with 100 sides. A triangle has exactly three (straight) sides; no more and no less. Having three sides means that the shape also has three internal angles and this explains the name.
No, quardrilateral means a shape having four sides, and triangle means a shape having 3 sides so no quardilateral is triangle * * * * * True, but the question had nothing to do with triangles! A kite or a rhombus are quadrilaterals but they are not rectangles. So, although some quadrilaterals are rectangles, not all are.
A right angled triangle is an example of a shape with exactly 2 perpendicular sides.
scalene triangle.
An equilateral triangle
yes but some time it depends on the shape of the triangle
Isosceles means having equal "legs". It can be a triangle, trapezium or a shape with more sides.
Triangle means 3 angles. No other shape exists and any three angle shape is a triangle
A 3 dimensional triangle is called a pyramid, otherwise a 2D three sided polygon shape is exactly what you called it, a triangle.
NO!!! The word' congruent' means 'exactly the same' , both in size, area and shape. Since a triangle has 3 sides, and a square has four sides, they are NEITHER the same size NOR shape. They are NOT congruent, but INCONGRUENT. Do NOT confuse with 'similar'. 'Similar' means same shape, same angles, BUT different area. Both terms have specific mathematical meanings, so be careful.
