A SQUARE with side = 14
find the diagonal.

14√2

Step-by-step explanation:

A square with a diagonal automatically makes a 45 45 90 triangle (angles) meaning that the two legs are x and the hypotenuse (diagonal) is x√2

If 14 = x then the diagonal is 14√2

You could also solve with the pythagorean theorem

a^2 + b^2 = c^2    so in this case

14^2 + 14^2 = c^2

196 + 196 = c^2

392 = c^2            

√392 = √c^2     the 392 is divisable by 196 so you can divide that out as 14

14√2 = c

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
