    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


    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
