hey guys sorry for not clarigying i found the ratio for taking alpha as for triangle abc and for raingle pda , then i tried for dbq , alpha is obviously outside of triangle dbq so it cant be that then i tried seeing if the value of sine is equal to any one of the angles inside dbq , but to no avail

how are the triangles similar by aa criteria ?

lavish heron
#

So, prove that the triangle with sides b, d, q is similar to the one with sides a, d, p.

#

both have a 90 degree angle in them but what else do they share

lavish heron

#

the red one is 90 - alpha and green one is 90 - angle bq

lavish heron
#

So, what is the green angle?

split hamlet
#

in the angle sum prop of abc ?

lavish heron
#

What?

split hamlet
#

, im confused

lavish heron
#

What is the sum of the green and red angles?

split hamlet
#

green + red =180 -(alpha +angle bq)

#

...... am i wrong ...??

#

the silence is killing me

lavish heron
#

Look at the picture.

#

The sum of red and green angles is 90°.
