A. The angles at the intersection of the two lines can be proven to be congruent and complementary . so they meet at a right angle and the lines are perpendicular.
<u>Step-by-step explanation:</u>
In above question, In order to find whether AB ⊥ CD, Using compass construction & rounder , keep the tip at A and cut arcs at line CD . Follow the same process again with tip at B and cut arcs at line CD . Do this both sides of Line CD i.e. on left side of AB & on right side of AB. Now, join the intersection points of both side arcs which are intersecting each other. Now, to prove both are right angle to each other i.e. AB ⊥ CD , can be done by proving congruent and complementary , so they meet at a right angle and Hence , the lines are perpendicular i.e. AB is inclined to CD at angle of 90°.
Answer:
The area of a circle with a circumference of 4.6 is 1.684
Step-by-step explanation:
I think its that. Im not sure ;-;
Answer:
(-10,-4)
Step-by-step explanation:
The point is moved to the other side of the y axis.
The y coordinate would stay the same and the x coordinate would move the same number of units but on the opposite side (that's why its -10).
Orange is 9.
so 9/(7+4+9 ) times 100.
the answer is 45%
