The meaning of the options are:
- Acute: an angle between 0 and 90 degrees;
- Straight: and angle of 180 degrees;
- Right: an angle of 90 degrees
- Obtuse: an angle of more than 90 degrees
So, AFB is acute, because it's and angle of 48 degrees, between it's complementary to BFC and they for a right angle.
DFB is obtuse, because it's the right angle DFC plus the angle CFB
Finally, CFD is right (we can only deduce this by looking at the picture)
Answer:
The correct option is A.
Step-by-step explanation:
It is given that DEFG is a parallelogram.
Draw the diagonals DF and EG. Place point H where DF and EG intersect.
In triangle HGD and HEF
,
∠HGD ≅ ∠HEF (Alternate Interior angle)
∠HDG ≅ ∠HFE (Alternate Interior angle)
By the definition of a parallelogram, the opposite sides of a parallelogram are congruent.
DG ≅ EF (Opposite sides of parallelogram)
According to ASA postulate, two triangles are congruent if any two angles and their included side are equal in both triangles.
So, by using ASA criterion for congruence we get,
ΔDGH ≅ ΔFEH
Since corresponding sides of congruent triangles are congruent, therefore
GH ≅ EH (CPCTC)
DH ≅ FH (CPCTC)
Option A is correct.
Answer:
