Question b of 10which of the following describe an angle with a vertex at a? check all that applyo a. labcов. савd dooo c_baco d. zacb​

 The correct options are

(A) DEF.

(C) FED.

Choices:

A.DEF B.DFE C.FED D.EFD

 The correct options are

(A) DEF.

(C) FED.

Step-by-step explanation:  We are given to select the correct options that describes an angle with a vertex at E.

We know that

while writing the name of an angle, we always write the vertex in the middle and the points on the two legs of the angle are written on the two sides, left and right.

Option (A):  DEF.

Since the vertex E is written in the middle and the points D and F on the two legs ED and EF are written on the left and right side respectively,

so DEF describes an angle with vertex E.

Option (B):  DFE.

Since the vertex E is not written in the middle, so DFE does not describes an angle with vertex E.

Option (C):  FED.

Since the vertex E is written in the middle and the points F and D on the two legs EF and ED are written on the left and right side respectively,

so FED describes an angle with vertex E.

Option (D):  EFD.

Since the vertex E is not written in the middle, so EFD does not describes an angle with vertex E.

Thus, the correct descriptions of an angle with vertex E are DEF and FED. The angle is shown in the attached figure below.

Options (A) and (C) are CORRECT.

A and B

Step-by-step explanation:

A and D

Step-by-step explanation:

See I cannot explain you by diagram as I cannot make it here but the short trick is that the angle with the vertex you are looking for should be in the centre.

Here, it is XYZ and ZYX

answer: b and c

step-by-step explanation:

Answer

B., C.

Step-by-step explanation:

Since the 'E' in the middle

it represents that the angle forms at the vertex E

C and D

Step-by-step explanation:

In naming an angle using 3 letters the letter denoting the vertex is always located in the middle of the 3 letters

Thus ∠BAC and ∠CAB

D) BAC is the correct answer as A is at the middle.

The vertex of angle is the middle letter.

E is the vertex so the answers are:

A and C

X

Step-by-step explanation:

X and Y make up a graph
