The calculation of the triangle area will depend on the type of triangle as well as the facts that the problem says. Below Software will share the simplest calculation, applied to normal, square, weighing, even…
The calculation of the triangle area will usually apply to square, balanced, and regular triangles. However, in those special cases, you should apply your own formula faster. Here will be the specific cases to help you apply the fastest and simplest to your geometry problem.
The formula for calculating the area of a class 10 triangle.
HOW TO CALCULATE THE AREA OF THE TRIANGLE
+ How to calculate the normal participation area: Triangles are usually triangles with 3 unequal sides.
S = 1⁄2 a.h (where a is the length of the bottom edge, h is the height corresponding to the bottom edge)
The area of the triangle is usually half the product of the height multiplied by the bottom edge.
Example: Calculate the area of a triangle with side a = 10 cm, the height corresponds to side a, denoted h = 12 cm. Calculating the area of the triangle?
Cup:
Applying the formula for calculating the area of the common triangle we have: S = 1⁄2 a.h = 1⁄2 x 10 x 12 = 60 cm2
The answer to the problem is 60 cm2
+ How to calculate the area of right triangle: A right triangle is a triangle with 1 right angle.
S = 1⁄2 a.b (where a and b are 2 right-angled sides)
The area of the right triangle is half the product of 2 right-angled sides. In the case of right triangles with 2 equal right-angled sides called isosceles right triangles. The calculation of the area will be S = 1⁄2 a2 where a is the right angle side length.
Example: Let the right triangle ABC be right at B. Side AB is half the side BC and equal to 3 cm, calculating the area of the triangle.
Cup:
The problem shows that 1 right-angled side AB = 3 cm, side AB is again equal to 1 half of the side BC, deducing that the side BC = 2 x AB = 2 x 3 = 6 cm.
From here, applying the formula for calculating the area of a right triangle, we get: S = 1⁄2 a.b = 1⁄2 x 3 x 6 = 9 cm2
+ How to calculate the area of the isosceles triangle: An isosceles triangle is a triangle with 2 equal sides.
S = 1⁄2 a.h (where a is the length of the bottom edge, h is the height corresponding to the bottom edge)
The area of the equilibrium triangle equals half the product of the height multiplied by the base edge corresponding to the height. In this case, you use the formula to calculate the area as a normal triangle.
Example: Given the isosceles triangle ABC at B, let H be the midpoint of the side BC, side AC = 9 cm, BH = 12 cm. Calculate the area of the triangle ABC.
Cup:
The problem indicates the height BH = 12 cm, the bottom edge AC = 9 cm.
Apply the formula for calculating the area we have: S = 1⁄2 a.h = 1⁄2 x 12 x 9 = 54 cm2
+ How to calculate the area of equilateral triangles: Equilateral triangles are triangles with 3 equal sides and 3 equal angles, 60 degrees each.
S = a2√3/4 (where a is the degree for 1 side of the triangle)
The area of the equilateral triangle is equal to the square of one side multiplied by root 3 divided by 4.
Example: Calculate the area of the equilateral triangle side by 5 cm.
Cup:
Immediately applying the formula for calculating the equilateral triangle area, we immediately have the triangle area:
S = a2√3/4 = 25√3/4 = 10.825 cm2
The above are the specific cases of triangles and the simplest calculation of the triangle area. In addition, for cases where the problem indicates the triangle edge and angles, you can apply the trigonometric formula to calculate the triangle area that Software will share in the following articles.
