Regarding Types of Triangles

Triangle : Triangles are plane figures that have only three sides and three corners.
Types of Triangles :
1. Isosceles Triangle has two sides that are of same length and the two angles are of same size.
2. Equilateral triangle :In Equilateral triangle all the sides are of same length and all the angle are of same size . Sum of angles of a triangle is always 180 degrees.
3. Acute triangle : Acute triangles have no angles greater than or equal to 90 degree
4. Obtuse Triangle : Obtuse triangle have one angle that is greater than 90 degree.
5. Right Triangle : This triangle has one 90 degree angle and two acute angles.

Thank You for posting these kinds of questions on this site it will help many of the parents and children as well. By these questions it will be and easy task for the parents to make their children learn about the particular subject this is a good question and my one of the suggestion is that you should also give the children an answer key so that they can match their answer with the questions and they can know what is the correct answer for that particular question and can remember it for a long period of time. And it is a great way of increasing the IQ of a child so that he or she can remember a question for a long period of time thanking you again for posting these questions and please post more and more questions of these types.
