Question

Can Someone Check my answers ****** I'll give a medal

Answer 1

A right triangle has

A) three sides with the same length

B) two sides that are parallel

C) at least two congruent sides <---- My answer

D) two sides that are perpendicular

Answer 2

"right" triangle means one of the angle in that triangle is 90 degrees.

when 2 sides are perpendicular, the angle included between them will be 90 degrees.

Answer 3

so its not C :)

Answer 4

I remember answering this question before but i forgot what I put I was debating on D or C.

Answer 5

Ok D?

Answer 6

yup.

Answer 7

Ohh thanks :)

Answer 8

welcome ^_^

Answer 9

Line AB contains points A (3, −2) and B (1, 8). The slope of line AB is ?
A) −5

b) negative 1/5 <---- My answer

C) 1/5

D) 5

Answer 10

nopes, use this

\The slope of the line through points (x1,y1) and (x2,y2) is given by :
\(\huge m=\frac{y_1-y_2}{x_1-x_2}\)
now,just put the values and find m.

Answer 11

y1 - y2 = -2 -8
x1-x2 = 3-1

Answer 12

-10/2

Answer 13

yes

Answer 14

do i divide it ?

Answer 15

yes

Answer 16

-5

Answer 17

correct :)

Answer 18

Line AB contains points A (−3, 5) and B (−3, 3). Line AB has a slope that is

A) zero

B) undefined <---- My answer

C) positive

D) negative

Answer 19

correct :)

Answer 20

When the coordinates (1, 1), (4, 4), (7, 1), and (4, -2) are joined, which shape is formed?

A) Parallelogram

B) Rectangle

C) Trapezoid

D) Square <--- my answer

Answer 21

yes, it is square :)

Answer 22

Find the perimeter of the following shape, rounded to the nearest tenth:

Answer 23

A) 17.9

B) 18 <--- my answer

C) 18.6

D) 19.1

Answer 24

2 (sqrt (16+4)+sqrt(25+1))
is 19.14

Answer 25

oh so its D?

Answer 26

yes

Answer 27

Point E is located at (2, −3) and point F is located at (−2, −1). Find the y value for the point that is 3 over 4 the distance from point E to point F.

A) 1.75

B) 0.5

C) −2

D) −1.5 <---- My answer

Answer 28

I was wondering If you could help me understand this one @hartnn

Answer 29

(-3-(-1)) (3/4) = -3/2 = -1.5
so yes, you're correct :)

Answer 30

Ohh I thought I was going to get it wrong.

Answer 31

Segment RS is an altitude of triangle P QR. Find the area of the triangle.

Answer 32

A) 15.5 <---- My answer

B) 16

C) 17.5

D) 18

Answer 33

1/2 *8* 4

Answer 34

that came from Area of triangle = 1/2 * base * height

Answer 35

Can you explain it to me a bit more please

Answer 36

PQ is the base of that triangle
can you find the length of PQ ?
using distance formula or any technique ?

Answer 37

ok I got B or C?

Answer 38

but Im debating between those two

Answer 39

1/2 *8* 4 =16

Answer 40

So B?

Answer 41

yes

Answer 42

I appreciated it for you helping me there are three more questions I need you to check. And then we're done

Answer 43

Find the x value for point F such that DF and EF form a 1:3 ratio.

Answer 44

A) 0.75 <--- Debating

B) −1

C) 2

D) −1.75 <-- Debating

Answer 45

(nx1 +mx2)/(m+n)
so calculate

[(-3)*3 - 1*2 ]/(1+3)

Answer 46

I got 2.75

Answer 47

thats because there's a sign mistake
****
[(-3)*3 + 1*2 ]/(1+3)

Answer 48

[(-3)*3 + 1*2 ]/(1+3) =-1.75

Answer 49

thats what I got

Answer 50

D is the correct ?

Answer 51

yes

Answer 52

Find the x value for the point that splits segment CD in half if point C is located at (−2, 4) and point D is located at (3, 7).

A) 2.5

B) 1

C) 0.5 <--- My answer

D) 3

Answer 53

yes :)

Answer 54

Quadrilateral ABCD has congruent angles and opposite sides that are congruent. What classification can be given to ABCD?

A) Parallelogram

B) Rectangle

C) Rhombus <--- My answer

D) Square

Answer 55

rhombus has congruent sides, not angles.

Rectangle has congruent angles :)

Answer 56

ohh so its a rectangle ?

Answer 57

yes

Answer 58

may I ask how?

Answer 59

all angles congruent means all angles are 90 degrees,
only squares and rectangles have that property (not rhombus)

"opposite sides that are congruent"
squares has all sides congruent.
thats why answer is rectangle only.

Answer 60

Thank you so much for helping me and I really appreciated for your time and effort. Thank you again.

Answer 61

Ohh ok I get it now thank you again :)

Answer 62

your welcome ^_^
