What is a triangle PPT?
3. TRIANGLES A triangle is a 3-sided polygon. Every triangle has three sides, three vertices and three angles. On the basis of sides of a triangle, triangles are of three types, An Equilateral Triangle, An Isosceles Triangle and A Scalene Triangle. All triangles are convex and bicentric.
What is the longest side of a scalene triangle called?
hypotenuse
The longest side of a right- angled triangle is called the hypotenuse.
What are the types of triangles?
Based on the length of the sides, triangles are classified into three types:
- Scalene Triangle.
- Isosceles Triangle.
- Equilateral Triangle.
What is triangle type triangle?
The six types of triangles are: isosceles, equilateral, scalene, obtuse, acute, and right. An isosceles triangle is a triangle with two congruent sides and one unique side and angle. An equilateral triangle is a triangle with three congruent sides and three congruent angles.
What is triangle and its types?
Triangles are shapes with three sides. A triangle’s type depends on the length of its sides and the size of its angles (corners). There are three types of triangle based on the length of the sides: equilateral, isosceles, and scalene. The green lines mark the sides of equal (the same) length.

What is an unequal triangle called?
Scalene. A scalene triangle has three different angles and none of its sides are equal in length.
What is a 3D pyramid?
A pyramid is also a three-dimensional (3D) shape. It has a polygon base and flat (triangular) sides that join at a common point (called the apex). The Egyptian pyramids are square-based pyramids, but there are several other types of pyramids, each with a different polygon as its base.
What are some examples of triangle?
Bermuda Triangle. The Bermuda Triangle,also known as the Devil’s triangle,is a loosely defined triangular area in the Atlantic ocean,where more than 50 ships and 20 aircraft
What are types of triangle according to the angles?
Types of Triangles Based on Angles Acute Triangle. An acute triangle is a triangle whose all the three interior angles are acute. Obtuse Triangle. Obtuse triangles are those in which one of the three interior angles has a measure greater than 90 degrees. Right Triangle. A right triangle is a triangle in which one of the angles is 90 degrees.
Which type of triangle has three different lengths?
Scalene is the only triangle that has 3 different integer length sides. Isosceles triangles have 2 congruent sides and a base length. An equilateral triangle has all of its sides equal to each other.
What are two different triangles?
As we have mentioned previously, there are two types of the triangles, the contracting and the expanding triangles and the most common type of the triangle that appears is the contracting triangle.
