For a project in his Geometry class, Mamadou uses a mirror on the ground to measure the height of his school's football goalpost

andreev551 [17]

Answer:

Height of the goalpost is 9.25 m.

Step-by-step explanation:

As per the rule of reflection in physics,

Angle of incidence = Angle of reflection

As we can see in the picture attached, both the angles (θ) are equal.

m∠ACB = m∠ECD = 90° - θ

m∠ABC = m∠ADC = 90°

Therefore, both the triangles ΔABC and ΔEDC will be similar.

And by the property of similar triangles, their corresponding sides will be proportional.

$\frac{AB}{ED}= \frac{CB}{CD}$

$\frac{1.75}{ED}=\frac{2.6}{13.75}$

ED = $\frac{1.75\times 13.75}{2.6}$

ED = 9.25 m

Height of the goalpost is 9.25 m.

For what reason would we use the distance formula to determine the type of quadrilateral?

Whitepunk [10]

Answer:

Sides/diagonals are congruent

Step-by-step explanation:

If the distance formula is used to determine the type of quadrilateral, then we are interested in knowing whether the opposite sides are congruent or adjacent sides are congruent.

We can also use the length of diagonals to determine which type of quadrilateral.

For instance the square has all sides equal.

The diagonals of the rectangle are congruent.
