To prove that <span>AEC≅ AED, we need to write following proofs or statement reasons.
It is given that points C and D are equidistant to point A. Hence,
</span><span>AD ≅ AC
Next, </span><span>CAE ≅ DAE. AE is the common side or the included side.
</span><span>
Then, </span><span>AE ≅ EA by Reflexive Property of Congruence as it is congruent to itself.
Lastly, </span><span>EAD ≅ EAC by Symmetric Property of Congruence as these triangles are mirror image of each other.
</span>
Therefore, we can conclude that AEC≅ AED by SSS or Side-Side-Side. That is when all sides of triangles are congruent then both triangles are deemed to be equal.
Answer:
Length of NM is 36 cm
Step-by-step explanation:
Length of MN + Length of NO = Length of MNO (Or only MO)


cm
Thus, length of MN is equal to length of NO i.e 36 cm
The line MNO has point N, that bisect it into two equal half.
Thus, the line MNO has two parts
Total length of line MNO = MN + NO =
cm
All quadrilaterals have a total of 360 degrees so...
90+76=163
163+111=274
360-274=86
The measurement for the 4th angle would be 86 degrees
180° is the answer for this
