From the diagram, ∠A, ∠F, and ∠E form a straight line, therefore the following can be deduced:
∠A + ∠F + ∠E = 180° (angle in a straight line)
∠H = ∠A (corresponding angles)
m∠G = m∠E (corresponding angles)
m∠F = m∠C (vertical angles)
What is an angle?
An angle is formed from the intersection of two or more lines. Types of angles are acute, obtuse and right angle.
From the diagram:
∠A, ∠F, and ∠E form a straight line. Hence:
∠A + ∠F + ∠E = 180° (angle in a straight line)
∠H = ∠A (corresponding angles)
m∠G = m∠E (corresponding angles)
m∠F = m∠C (vertical angles)
