What other term describes figure abcd

Solution:

It is given that the figure given is Rhombus.

Properties of rhombus

1. All Sides are equal.

2. Opposite Angles are equal.

3. Diagonals Bisect each other.

4. Opposite sides are parallel

Now , if you will consider four sided convex polygons ,starting from Parallelogram, Rhombus, Rectangle, Square and Kite

Only Quadrilateral Square satisfies all the properties of Rhombus.

Rhombus Can be Named as Quadrilateral Square.Also remember one Statement, a square can be a Rhombus but not Vice versa.

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
