Statement

Reason

Points A, B, and C form a triangle.

given

Let DE be a line passing through B and parallel to AC. definition of parallel lines

23 – 25 and 21 - 24

m21 = m 24 and 23 = m25

m24+ m2 2 + 25 = 180°

mZ1 + Z2 + m23 = 180°

Is (-a + b)² = a² - 2ab + b² right or wrong, and why?

antiseptic1488 [7]

Answer:

$\huge\boxed{\sf Right.}$

Step-by-step explanation:

$(-a+b)^2$

Let's apply the formula (x+y)² = x² + 2xy + y²

Here, x = -a and y = b

So,

= (-a)² + 2(-a)(b) + (b)²

= a² - 2ab + b²

Hence, it has been proved that (-a + b)² = a² - 2ab + b².
