Answer:
the third or fourth one probably
Step-by-step explanation:
You have not provided the options, therefore, I can not provide an exact answer.
However, I will help you with the concept
In a triangle, the circumcenter is defined as the point of intersection of the three perpendicular bisectors in the triangle
The circumcenter is characterized by the following:
1- The circumcenter is the center point of the circumcircle
2- The circumcenter is equidistant from the three vertices of the triangle
<u>3- Position of circumcenter:</u>
in acute triangle ........> it lies inside the triangle
in right-angles triangle .......> it lies at the midpoint of the hypotenuse
in obtuse triangle ..........> it lies outside the triangle
Hope this helps :)
Answer:
∆BDC ~ ∆EDA
Step-by-step explanation:
From the given figure in the diagram contained in the question:
=>Angle EDA is congruent to angle BDC
=>Angle E is congruent to angle B
=>Angle A is congruent to angle C
==>Therefore, the similarity statement that can be written to compare the two triangles = ∆BDC ~ ∆EDA
The symbol "~" means "similar to".
Thus, ∆BDC is similar to ∆EDA
