How do I know if it’s similar, congruent or neither?

Mathematics
1 answer:
Phantasy [73]2 years ago
5 0

Answer:

These two triangles are congruent.

Step-by-step explanation:

You know this bc the markings on the drawing show that Angle B and Angle D are congruent. Also that AB is parallel to CD. This means that Angle BAC and Angle DCA are congruent by ALTERNATE INTERIOR ANGLES. Also, AC is congruent to itself. That makes the two triangles congruent by ANGLE-SIDE-ANGLE.

Now, you need to know that "congruent" triangles (and shapes in general) are the same size and shape. "Similar" triangles (shapes) are the same shape but not necessarily the same size.

It takes Tim 5 hours to make a vase, and it takes him 9 hours to
LenKa [72]

Answer:

D. 9 vases and 13 teapots

Step-by-step explanation:

From the information given, you can write the following equations:

x+y=22 (1)

5x+9y=162 (2)

x=number of vases

y= number  of teapots

First, you have to isolate x in (1):

x=22-y (3)

Then, you have to replace (3) in (2) and isolate "y":

5(22-y)+9y=162

110-5y+9y=162

110+4y=162

4y=162-110

y=52/4

y=13

Now, you can replace the value of y in (3):

x=22-y

x=22-13

x=9

According to this, the answer is that Tim made 9 vases and 13 teapots.

Proving Parallelogram
AysviL [449]

Answer:

Soln.

Given that we have proven:AB =CD and BC=DA

we will be said that the A and C is the angle of 90° and we will add the letters to get the results so let's started the A+90°+ 90°+ B+C+ D=90°

A+180°+B+C+D

180°+90°

=270°
