The line across from the right angle is called a?
In a right angle triangle, the line across from the riht angle is called the hypotenuse.
What does one line of symmetry means?
If you had a circle and you halved it, exactly in the middle, then that line would be a line of symmetry! And it is the same with a square. If you halve it exactly in the middle then that would be called a line of symmetry! And then all the lines of symmetry in a square are down, across, diagonal from the left and then diagonal from the right! But in a circle there are LOTS of lines of symmetry!
How do you work out the perimeter of a semi circle?
Measure the diameter of the circle,this is a line taken right across the circle that goes through the centre. Now multiply by pi =3.142 and divide by 2 to get the length of half the circumference.
What is a line through a circle called?
A line that goes through a circle is a secant line. (Remember that a line is infinitely long.) Anyline that passes through a circle is a secant line, whether it passes through the center of the circle or not. Compare this to a line segment with endpoints on the circumference of a circle. That segment is called a cord of that circle. If the cord of a circle passes through the center of that circle, it is a diameter of that circle, which is the longest cord of the circle.
A line segment that intersects with two points on a circle is called what?
A line segment that intersects with or joins two points on a circle is called a chord.
