Answer 1

Step-by-step explanation:

$\huge{ \maltese \: \sf{ \pink{Solution : }}}$

(i)

As if we see the figure,

∠a = ∠b ( corresponding angles )

40° = ∠b

The corresponding angles are equal.

∴ ∠b measures 40° .

(ii)

∠b and ∠c are alternate interior angles. As, L II M and n is a transversal.

Different types of angles:

Acute angle:

An angle whose measure is less than 90 degrees.

Right angle:

An angle whose measure is 90 degrees.

Obtuse angle:

An angle whose measure is bigger than 90 degrees but less than 180 degrees. Thus, it is between 90 degrees and 180 degrees.

Straight angle:

An angle whose measure is 180 degrees. Thus, a straight angle look like a straight line.

Reflex angle:

An angle whose measure is bigger than 180 degrees but less than 360 degrees.

Full rotation angle:

An angle whose measure is 360 degrees. A full rotation angle consists of 4 right angles.
