how can we find angles from a triangle
Answers
Explanation:
From where two lines meet together.
✈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
