Answer:
C. HA (Hypotenuse angle congruence).
Step-by-step explanation:
We have been given a diagram of two right triangles. We are asked to choose the correct congruence theorem for our given triangles.
In our triangles ABC and DEF we have,
We can see that side length AB is hypotenuse of triangle ABC and side length DE is hypotenuse of triangle DEF.
Angle A and angle D are acute angles (less than 90 degrees) as we have one right angle in our both triangles and measure of other two angles will be 90 degrees in both triangles by angle sum property of triangles.
Hypotenuse angle theorem states that two right triangles are congruent, if the hypotenuse and an acute angle of one right triangle are congruent to the hypotenuse and an acute angle of another right triangle.
Therefore, by HA congruence triangle ABC is congruent to triangle DEF and option C is the correct choice.
Answer:
y = 54
Step-by-step explanation:
180 - 74 = 108 (this is the sum of 2 unknown angles)
108/2 = 54 ( This is the measure of each y angle)
Hope this helps!
Eyeballing it, it looks like the center is (2,4), two to the right, four up.
Let's say the minimum point on the circle is (2,1). So a radius is the distance from the center to there. It's a vertical line, 3 units in length.
We plug into the equation
