Question

Jk is a line of symettery if the hexagon angel bjg = angel ckf =140 work out the size of angel kfe you muust show all your working

Answer 1

To find the size of angle KFE, we can use the fact that the angles BJG and CKF are both equal to 140 degrees. Since JK is the line of symmetry, the angles BJG and CKF are congruent. This means that angle JKF is also 140 degrees.

Step-by-step explanation:

To find the size of angle KFE, we can use the fact that the angles BJG and CKF are both equal to 140 degrees. Since JK is the line of symmetry, the angles BJG and CKF are congruent. This means that angle JKF is also 140 degrees.

Now, we can use the fact that the angles of a triangle add up to 180 degrees. Since angle JKF is 140 degrees, angle KFE must be 180 - 140 = 40 degrees.

So, the size of angle KFE is 40 degrees.
