Study with Quizlet and memorize flashcards containing terms like A triangle with no equal sides is called a scalene triangle, The sum of the measures of the interior angles a triangle is 180°, An exterior angle of a triangle is equal to the sum of the two remote interior angles and more.
2D means 2 Dimensional, and includes shapes like triangles, squares, rectangles, circles and more! Here we show the moost common 2D shapes.
A triangle is a polygon with three corners and three sides, one of the basic shapes in geometry. The corners, also called vertices, are zero-dimensional points while the sides connecting them, also called edges, are one-dimensional line segments.
A triangle is a 3-sided polygon sometimes (but not very commonly) called the trigon. 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 ...

As we discussed in the introduction, a triangle is a type of polygon, which has three sides, and the two sides are joined end to end is called the vertex of the triangle. An angle is formed between two sides.This is one of the important parts of geometry. Some major concepts, such as Pythagoras theoremand trigonometry, are dependent on triangle pro...
There are three angles in a triangle. These angles are formed by two sides of the triangle, which meets at a common point, known as the vertex. The sum of all three interior angles is equal to 180 degrees. If we extend the side length outwards, then it forms an exterior angle. The sum of consecutive interior and exterior angles of a triangle is sup...
Each and every shape in Maths has some properties which distinguish them from each other. Let us discuss here some of the properties of triangles. 1. A triangle has three sides and three angles. 2. The sum of the angles of a triangle is always 180 degrees. 3. The exterior angles of a triangle always add up to 360 degrees. 4. The sum of consecutive ...
On the basis of length of the sides, triangles are classified into three categories: 1. Scalene Triangle 2. Isosceles Triangle 3. Equilateral Triangle On the basis of measurement of the angles, triangles are classified into three categories: 1. Acute Angle Triangle 2. Right Angle Triangle 3. Obtuse Angle Triangle
A perimeter of a triangle is defined as the total length of the outer boundary of the triangle. Or we can say, the perimeter of the triangle is equal to the sum of all its three sides. The unit of the perimeter is same as the unit of sides of the triangle. If ABC is a triangle, where AB, BC and AC are the lengths of its sides, then the perimeter of...
The area of a triangleis the region occupied by the triangle in 2d space. The area for different triangles varies from each other depending on their dimensions. We can calculate the area if we know the base length and the height of a triangle. It is measured in square units. Suppose a triangle with base ‘B’ and height ‘H’ is given to us, then, the ...
In case, if the height of a triangle is not given, we cannot be able to use the above formula to find the area of a triangle. Therefore, Heron’s formula is used to calculate the area of a triangle, if all the sides lengths are known. First, we need to calculate the semi perimeter (s). s = (a+b+c)/2, (where a,b,c are the three sides of a triangle) N...
Question 1: If ABC is a triangle where AB = 3cm, BC=5cm and AC = 4cm, then find its perimeter. Solution: Given, ABC is a triangle. AB = 3cm BC = 5cm AC = 4cm As we know by the formula, Perimeter = Sum of all three sides P = AB + BC + AC P = 3+5+4 P = 12cm

Polygon is the combination of two words, i.e. poly (means many) and gon (means sides). A minimum of three line segments is required to connect end to end, to make a closed figure. Thus a polygon with a minimum of three sides is known as Triangle and it is also called 3-gon. An n-sided polygon is called n-gon.
A triangle is a closed, 2-dimensional shape with 3 sides, 3 angles, and 3 vertices. A triangle is also a polygon. The above figure is a triangle denoted as ABC.
