Answer:
The equation for the circle is:
Step-by-step explanation:
Here, let us assume the two end points of the diameter are:
P (3,-1) and Q (-2,-1)
Now, as we knew diameter is the chord that passer through the center of the circle.
⇒ Mid point of DIAMETER = Center coordinates of the Circle
Let us assume O(x,y) is the center of the line segment PQ.
So, by MID POINT FORMULA:
⇒ The center coordinates of the circle = O(0.5,-1) ...... (1)
Now, RADIUS = Half of DIAMETER
Using DISTANCE FORMULA:
So, Radius = 5/2 = 2.5 units
Now, the equation of circle with radius r and center coordinate ( h,k) is given as:
Substitute r = 2.5 and (h,k) = (0.5,0) we get:
Hence the equation for the circle is:
△ABC has interior angles with measures x°, 100°, and 70°.
By using angle sum property, which states that the sum of measures of all three angles is 180 degrees.
Now, △DEF has interior angles with measures y°, 70°, and 20°.
By using angle sum property,
Now, we can say that,
"The two triangles are not similar because x≠y"
As one angle of measure 70 degree is common in both the triangles.
If 'x' would be equal to 'y' , then we could say that the triangles are similar by AA criteria.
Therefore, the two triangles are not similar because x is not equal to y.
