Question 13

Mathematics Basic Geometry Easy

If ends of base of an isosceles triangle are at \( (2,0) \) and \( (0,1) \) and the equation of one side is \( x=2 \) , then the orthocentre of the triangle is

(A) \( (3 / 2,3 / 2) \)
(B) \( (5 / 4,1) \)
(C) \( (3 / 4,1) \)
(D) \( (4 / 3,7 / 12) \)
View Dynamic Solution & Explanation
Correct Solution: Option B

Step-by-step Solution:

Form the figure, \(2^2+(y_1−1)^2=y{_1}^2 \)
\(4+y_1^2+1−2y^1=y_1^2 \)
\( 5=2y_1 \)  or  \(  y_1=5/2 \)
Equation of the line form (2,5/2) to the given base is \( y−5/2=2(x−2) \) or \(2y−5=4(x−2) \)
At \(y=1\), \(−3/4=x−2\)
Or x=5/4
