Answer 1

Answer:

Measure of each of the angles of a square is:

a) Acute angle

b) Right angle

c) Obtuse angle

d) 180 degrees

Answer 2

Answer:

b) right angle

Step-by-step explanation:

Correct option is

B

90o

⇒  A square is a quadrilateral and we know sum of all four interior angles of a quadrilateral is 360o.

Let ABCD is a square.

All four sides and four angles of a square are equal.

∴  ∠A=∠B=∠C=∠D           ---- ( 1 )

⇒  ∠A+∠B+∠C+∠D=360o.

⇒  ∠A+∠A+∠A+∠A=360o        [ From ( 1 ) ]

⇒  4∠A=360o

⇒  ∠A=4360o

∴  ∠A=90o

⇒  ∠A=∠B=∠C=∠D=90o

∴  Each angle of a square has the measure of 90o.
