Step-by-step explanation:
Let ABC be the triangle where A(5,−2),B(6,4),C(7,−2)
Here AB = BC
Hence (5,−2),(6,4) & (7,−2) are vertices of isosceles triangle
Answer: yes it is an isosceles triangle
Step-by-step explanation:
Let the vertices be A(5,-2); B(6,4) and C(7,-2)
For the triangle to be an isosceles triangle, 2 of the sides should be equal to each other in magnitude
This implies that either AB = BC (or) BC = AC (or) AB = AC
We first need to find the length of the sides
Formula for finding the length of the side is
Where (x1, y1) and (x2, y2) are the points between which the distance is to be found
Substituting values of the vertices and solving, we get
AB =
=> AB =
=> AB =
Similarly while solving by substituting, we get
BC =
And
AC =
Therefore, AB = BC
Thus ABC is an isosceles triangle with AB = BC
