Two right triangles inside another large right triangle.

They are similar to each other.The area of the largest triangle

equals the area of the two inner triangles.

The sum of the 3 triangles total that of a quad.  Think about it like this the points of a triangle drawn on a map will show places where people were born raised and passed away.  For example for me in west Philadelphia born and raised

On the playground was where I spent most of my days

Chillin' out maxin' relaxin' all cool

And all shootin some b-ball outside of the school

When a couple of guys who were up to no good

Started making trouble in my neighborhood

I got in one little fight and my mom got scared

She said 'You're movin' with your auntie and uncle in Bel Air'.

I whistled for a cab and when it came near

The license plate said fresh and it had dice in the mirror

If anything I could say that this cab was rare

But I thought 'Nah, forget it' - 'Yo, homes to Bel Air'

I pulled up to the house about seven or eigth

And I yelled to the cabbie 'Yo homes smell ya later'

I looked at my kingdom

I was finally there

To sit on my throne as the Prince of Bel Air

The three triangles in the diagram are all right angle triangles.

All the triangle are similar but you need to associate the

correct angles.

To be similar, all you need is all angles being equal

both triangles

triangle RPQ is similar to RSP is similar to PSQ

ΔRPQ ~ ΔRSP ~ ΔPSQ

Big triangle RPQ

has right angle <RPQ

smaller triangles have right angles <PSR and <PSQ

Big triangle RPQ has <RPQ and <RQP = 90 - <RPQ

Little triangle PSQ has and <SQP =<RQP (they are the same angle)

and complementary angle <SPS = 90 - <SQP

but <SQP and <RPQ are the same

<SPS = 90 - < RQP

<SPS = <RQP

so now triangle RPQ is similar to PSQ

LIttle triangle has PSR has

<SRP which is the same angles <PRQ

and complementary angle

<SPR = 90- <SRP

and since <SRP is <QRP

<SPR = 90 - <RPQ = <RQP

again 3 angles are the same

QPR is similar to PSR

but you know

if A is similar to B

and A is similar to C

then B is similar to C

so all 3 triangles are similar.

all three are right triangles

how you know: the red squares tell you that SRP and QRP are right triangles

the fact that QR is a line segment

and rSp is a right angle

tell you that qSp is also a right triangle
