Answer:
HJ is diameter.
Step-by-step explanation:
Given Triangle HKJ is inscribed in the circle. we have to conclude about HJ if the triangle is a right triangle.
All the three sides are chord of the circle.
As given HKJ is right angled triangle i.e∠HKJ=90° and angle subtended by diameter in the semicircle is 90° implies HJ is diameter because if the HJ moves towards the angle then the given angle becomes acute and if moves away from the angle then the angle becomes obtuse which contradict the given information.
hence, the only possibility about the line HJ is that it is a diameter.
This exercise is about creating two-dimensional shapes. The resulting shape is a quadrilateral - Square. See the attached for the lines drawn.
What was noticed about the two lines drawn?
- The two lines are drawn each had parallel pairs; and
- They were perpendicular to one another.
When two lines intersect with one another such that they create a right angle, perpendicularity has occurred and both lines are said to be perpendicular to one another.
Hence:
- AB ⊥ BC
- BC ⊥ CD
- CD ⊥ DA; and
- DA ⊥ AB.
