Ok so you would say in your proof that AD=BC=DC=CA because it was given.
Then just say that BD=BD because of the reflexive property.
Lastly, write: Therefore, triangle ADB is congruent to triangle CDB.
Answer: f
Step-by-step explanation:
Answer:
27
Step-by-step explanation:
The inner angle is a right angle and equals 90, therefore the other two angles must add up to 90. N=27 makes one equal 33 and the other equal 57, adding up to 90.
Step-by-step explanation:
Quadrant I: Both values are positive.
Quadrant II: x-value is -ve, y-value is +ve.
On the x-axis: y-value is 0.
On the y-axis: x-value is 0.
The point (9, 0) has a y-value of 0.
=> It lies on the x-axis.
