Give ideas to make a PPT on Heron's formula and Triangle and its angles.Please i will br really vey very obliged to you.
Triangle and its angle :-
Triangles
![]() | A triangle has three sides and three angles |
![]() | The three angles always add to 180° |
Equilateral, Isosceles and Scalene
There are three special names given to triangles that tell how many sides (or angles) are equal.
There can be 3, 2 or no equal sides/angles:
![]() | Equilateral TriangleThree equal sides |
![]() | Isosceles TriangleTwo equal sides |
![]() | Scalene TriangleNo equal sides |
What Type of Angle?
Triangles can also have names that tell you what type of angle is inside:
![]() | Acute TriangleAll angles are less than 90° |
![]() | Right TriangleHas a right angle (90°) |
![]() | Obtuse TriangleHas an angle more than 90° |
Combining the Names
Sometimes a triangle will have two names, for example:
![]() | Right Isosceles TriangleHas a right angle (90°), and also two equal angles |
