Answer:
h =
Step-by-step explanation:
Formula for the area of a trapezoid is,
Area (A) =
Here b and c are the bases and 'h' is the height of the trapezoid.
2A =
2A = (b + c)h
Therefore, formula for the height of the trapezoid will be,
h =
If a diameter intersects a chord of a circle at a right angle, what conclusion can be made?
2 answers:
Answer:
The chord is bisected.
Step-by-step explanation:
see the attached figure to better understand the problem
In the circle of the figure
The diameter is the segment DE
The chord is the segment AB
PA=PB=r ----> radius of the circle
Triangles PAC and PBC are congruent right triangles by SSS
Because
PA=PB
PC is a common side
AC=BC ----> Applying Pythagoras Theorem
therefore
The chord AB is bisected
