To prove two triangles are similar, we only need two pairs of congruent angles.

The first pair of congruent angles could be the two right angles AED and GFC as shown by the square markers.

As for the other pair of congruent angles, we could pick on angle DAE and angle FGC, which are corresponding angles. The corresponding angles are congruent because of the vertical parallel line segments BA and FG

Once you have two pairs of congruent angles, you have effectively wrapped up the similarity proof. The specific theorem you use is the AA (angle angle) similarity theorem.

Find the measure of CP

dmitriy555 [2]

Given:

A figure ABCP.

To find:

The measure of CP.

Solution:

In triangles ABP and CBP,

$\angle PAB\cong \angle PCB$ (Given right angles)

$\angle ABP\cong \angle CBP$ (Given)

$BP=BP$ (Common side)

Now,

$\Delta ABP\cong \Delta CBP$ (By AAS property of congruence)

We know that the corresponding parts of congruent triangles are congruent.

$AP=CP$

$8=CP$

Therefore, the measure of CP is 8 units.

1. Choose the correct simplification of the expression −5x2(4x − 6x2 − 3).

nlexa [21]

1) <span>30x4 − 20x3 + 15x2

This is the answer to 1. Don't forget to rearrange the terms in ascending order. That can trip people up.

2) </span><span>x3 + 8x2 + 13

Don't forget to check the terms sign. The subtraction symbol switches them all. </span>

Very important question please solve it;(

matrenka [14]

Answer:

we know that 120 liked both places and 200 liked Pokhara. To find the number of students that only liked Pokhara 200-120=80 students

we know that 120 liked both places and 220 liked Chitwan. To find the number of students that only liked Chitwan 220-120=100 students

to find number of students that liked neither of places:

add

80+120+100=300. Subtract by total number of students.

350-300=50 students
