A triangle is one of the basic shapes of geometry: a polygon with three
corners or vertices and three sides or edges which are line segments. A
triangle with vertices A, B, and C is denoted ABC. In Euclidean geometry any three non-collinear points determine a unique triangle and a unique plane. (Source: Wikipedia)

A triangle has the base length of 20 cm and height is 23 cm. Find the area of the triangle in cm2.
Solution:
Given, base length (b) = 20 cm and height (h) = 23 cm.
Formula:
Area of the triangle = `(1 / 2)` * (b * h)
Substitute the given base length and height values in the above formula, we get
= `(1 / 2)` * (20 cm * 23 cm)
= 230 cm2
Answer:
Area of the triangle is 230 cm2
Triangle solver online example 2:
Find the area of the given triangle.
Solution:
From the given triangle ABC,
Base length (b) = 20 cm and height (h) = 23 cm.
Formula:
Area of the triangle = `(1 / 2)` * (b * h)
Substitute the given base length and height values in the above formula, we get
= `(1 / 2)` * (20 cm * 23 cm)
= 230 cm2
Answer:
Area of the triangle is 230 cm2
Triangle solver online example 3:
Find the x value of the given triangle.
Solution:
From the given triangle ABC,
Angle (B) = 60° and Angle (C) = 55° and Angle (A) = x
We know,
Sum of the angle in triangle is 180°
Therefore,
Angle (A) + Angle (B) + Angle (C) = 180°
Substitute the given values in the above formula, we get
x + 60° + 55° = 180°
x + 115 = 180°
Subtract 115 on both the sides, we get
x = 65°
Answer:
The final answer is Angle (A) = 65°
Triangle solver online example 4:
Find the x value of the given triangle.
Solution:
Given triangle is right triangle ABC.
From the triangle ABC,
AC = x, AB = 48, BC = 36
Using Pythagoras theorem,
AC2 = AB2 + BC2
Substitute the given values in the above formula, we get
x2 = 482 + 362
x2 = 3600
Take square root on both the sides, we get
x = 60
Answer:
The final answer is 60
