The exercise below is one that requires the proof that of certain dimensions using the rules of congruence. of triangles.

<h3>What does it mean for two angles to be congruent?</h3>

It simply means that both angles are similar in measure.

<h3>What is the required proof of the given problem?</h3>

It is given that ∠BAD=∠EAC

∠BAD+∠DAC=∠EAC+∠DAC [add ∠DAC on both sides]

Therefore ∠BAC=∠DAE

In △BAC and △DAE

AB=AD (Given)

∠BAC=∠DAE (Proved above)

AC=AE (Given)

Therefore △BAC≅△DAE (By SAS congruence rule)

Therefore BC=DE because Corresponding Parts of Congruent Triangles CPCT are congruent.

$\dfrac{ \dfrac{x+3}{4x^2-16} }{ \dfrac{2x^2+10x+12}{2x-4} }$

-----------------------------------------------------------------------------------
Write the divide fraction horizontally:
-----------------------------------------------------------------------------------

$= \dfrac{x+3}{4x^2-16} \div \dfrac{2x^2+10x+12}{2x-4}$

-----------------------------------------------------------------------------------
Factorise the numerators and denominators when possible:
-----------------------------------------------------------------------------------

$= \dfrac{x+3}{4(x+2)(x-2)} \div \dfrac{ 2(x + 3) (x + 2)}{2(x-2)}$

-----------------------------------------------------------------------------------
Convert the divide fraction to multiplication fraction
-----------------------------------------------------------------------------------

$= \dfrac{x+3}{4(x+2)(x-2)} \times \dfrac{2(x-2)}{2(x+3)(x+2)}$

-----------------------------------------------------------------------------------
Cancel the factors
-----------------------------------------------------------------------------------
$= \dfrac{1}{4(x+2)} \times \dfrac{1}{(x+2)}$

-----------------------------------------------------------------------------------
Combine to single fraction
-----------------------------------------------------------------------------------

$= \dfrac{1}{4(x+2)^2}$
