Answer:
1.A
2.D.
3.D
4.D
Explanation:
1.We are given that an angle
We have to find the name of given angle.
G is the vertices of given angle.
We know that vertices is always write in mid of the name of an angle
Suppose an angle ABC with vertices B.
There is B is in the middle of given name ABC.
Therefore, the correct name of given angle is Angle DGH.
Hence, option A is true.
2.We are given that CH=6
We have to find that statement for which is CH=6
We are given that SH=CM=4
HT=6
ST=4+6=10
CH=6
MH=MC+CH=4+6=10
Hence, MH=ST
Therefore, option D is true.
3.We are given that line DF and EG
We have to find the intersection of DF and EG
DF=DE+EF
EG=EF+FG
EF is common in both lines .Therefore, EF is the intersection of line DF and EG.
Hence, option D is true.
4.We are given that BD and CB
We have to find the intersection of BD and line BC
BD=BC+CD
BC is common in both therefore,BC is the intersection of both BD and line CB.
Hence, option D is true.
