Aug 24, 2023 · Easy: a triangle is a two-dimensional shape with three sides, three angles, and three vertices (the points where the sides connect). Because it has three or more sides, a triangle is also considered a polygon, so it belongs in the same shape family as the square, the rectangle, and even the decagon (which has ten sides!).
Triangles can be broadly classified into two types, which are: Triangles based on the lengths of their sides; Triangles based on their interior angles; These two triangle types are explained here along with their further classifications.

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.
Some real-life examples of triangles include sandwiches, traffic signs, cloth hangers, and a rack in billiards.
The above figures are non-examples of triangles. These shapescannot be called triangles as – 1. The first figure is four-sided. 2. The second figure is an open shape. 3. The third figure has a curved side.
A triangle has 3 sides. In triangle ABC, the sides are AB, BC, and CA.The angle formed by any two sides of a triangle is the angle of the triangle, denoted by the symbol ∠. A triangle has three angles. The three angles of the triangle ABC are ∠ABC, ∠BCA, and ∠CAB. T...The point of intersection of any two sides of a triangle is known as a vertex. A triangle has three vertices. In triangle ABC, the vertices are A, B, and C.The sum of all three interior angles of a triangle is always equal to 180⁰.The sum of the length of any two sides of a triangle is always greater than the length of the third side.The area of a triangle is equal to half of the product of its base and height.Triangles can be classified based on the length of the sides or their angle measurements. To classify triangles according to their angles, we measure each of their interior angles. Triangles can be classified by angles, as: 1. Acute Triangleor Acute-angled Triangle 2. Right Triangleor Right-angled Triangle 3. Obtuse Triangleor Obtuse-angled Triangl...
Q. Find the area of a triangle with a base equal to 10 cm and height equal to 8 cm. Ans. For the given triangle, base = 10 cm and height = 8 cm We know that, Area of a triangle= ½ (Product of base and height of a triangle) So, Area of the given triangle= ½ (10 x 8) = ½ (80) = 40 cm2 Q. Using the below figure, find the perimeter of the triangle ABC....
Conclusion Geometry is an important aspect of mathematics that requires in-depth learning. The concept of triangles is a fundamental topic in Geometry for young children. With interactive learning through detailed course material from SplashLearn, make your child learn about triangles, their types and properties, and practice with games andworkshee...
Triangle is a closed two-dimensional shape. It is a three-sided polygon. All sides are made of straight lines. The point where two straight lines join is the vertex. Hence, the triangle has three vertices. Each vertex forms an angle. There are three angles in a triangle.

Based on the measures of its interior angles, there are three types of triangles: acute (if all angles are less than 90°), right (if one angle is 90°), and obtuse (if one angle is more than 90°) The figure given below shows 6 types of triangles and their properties.
Oct 26, 2023 · Identify a triangle with one angle measuring \ (100^\circ\) and the remaining two angles totaling \ (80^\circ\). Answers: Acute Triangle. Equilateral Triangle. Obtuse Triangle. Triangles are categorized by side lengths (equilateral, isosceles, scalene) and angles (acute, obtuse, right).
All the properties of a triangle are based on its sides and angles. By the definition of triangle, we know that, it is a closed polygon that consists of three sides and three vertices. Also, the sum of all three internal angles of a triangle equal to 180°. Put your understanding of this concept to test by answering a few MCQs.
