Question

how can we find angles from a triangle​

Answer 1

Explanation:

From where two lines meet together.

Answer 2

✈Answer:-

✴What are the Angles of a Triangle?

✔The angle of a triangle is the space formed between two side lengths of a triangle.

✔A triangle contains interior angles and exterior angles. Interior angles are three angles found inside a triangle. Exterior angles are formed when the sides of a triangle are extended to infinity.

★To find the angles of a triangle, you need to recall the following three properties about triangles:

NOTE:-(refer to attachment)

»Triangle angle sum theorem:

✔ This states that the sum of all the three interior angles of a triangle is equal to 180 degrees.

a + b + c = 180º

✔Triangle exterior angle theorem: This states that the exterior angle is equal to the sum of two opposite and non-adjacent interior angles.

f = b + a

e = c + b

d = b + c

✔Straight line angles. The measure of angles on a straight line is equal to 180º

c + f = 180º

a + d = 180º

e + b = 180º
