The x-axis and the y-axis should always be perpendicular so that you can express any point in a 2-dimensional plane using an x value and a y value. They are perpendicular so that using them and visualizing is easier, so that x values have no impact on y values and vice versa, and so that formulas like the distance formula can be used. In general, right angles are much easier to work with than oblique or acute angles.

What is the angle between the two lines x0 and y0?
x0 and y0 aren't lines. Do you mean x=0 and y=0? If so, they are the y axis and the x axis, respectively, and the answer is 90 degrees as noted above.
Congruent angles always add up to 90 degrees?
Nope. It is complementary angles that add to 90 degrees.
What angle is always 90 degrees?
A right angle
What is the degree of the perpendicular lines?
always 90 degrees
What is always true about a right triangle?
There's always an angle that is 90 degrees
What planet is almost tilted 90 degrees on its axis?
The planet with an axis that tilts nearly sideways is Uranus. The title of is axis is 97.77 degrees (compared to Earth's with is 23.45 degrees.)
Is Earth habitable if its axis is tilted at 90 degrees angle?
It probably wouldn't be habitable, if the Earth's axial "tilt" were 90 degrees.
Which planet is tilted on its axis to almost 90 degrees angle?
Uranus.
Is each interior angle of a quadrilateral always 90 degrees?
No. in a rhombus the angles are not 90 degrees. also in a parallelogram they are not 90 degrees
What is meanning of x-axis?
It is the horizontal number line that intersects the y axis at 90 degrees on the Cartesian plane
Where is the origin in a graph?
At the point where the x and y axis intersect at 90 degrees.
Which planet's axis is tilted almost 90 degrees to its orbital plain?
Uranus.
What is a line that makes an angle of 90 degrees with a surface?
a line which is drawn parallel to either of axis makes 90 degree with other axis
What is the degree of a right angle?
the degree of a right angle will always be 90 degrees.
What does x-axis mean?
It's the horizontal line on the Cartesian plane that meets the y-axis at the origin at 90 degrees.
How does the tilt of earth's axis affect the number of daylight hours and temperature?
if the axis is over 90 degrees to the norh as it is in the summer
The point of intersection of the x and y axis?
They intersect at 90 degrees at the point of the origin
