What else can I help you with?
What are lines that cross each other at exactly one point and form four angles?
Intersecting lines
What is the sum of the measurements of the four angles formed by intersecting lines?
360
Do perpendicular lines have to cross each other?
Yes, being that perpendicular lines are by definition intersecting lines forming four 90 degree (right) angles.
What type of angle is formed by perpendicular lines?
Right angles are formed by perpendicular lines. If the lines would extend, to make two intersecting lines, they would form four right angles. Perpendicular lines are written like this: . From its shape, you can already tell that it forms at least two right angles.
Two lines that intersect to form four right angles?
Perpendicular lines
Do intersecting lines form four pairs of complementary angles?
No, intersecting lines form four pairs of supplementary angles
Two intersecting lines that form four right angles?
Perpendicular lines
What does two intersecting perpendicular lines form?
They form four right angles.
Do intersecting lines form four pairs of supplementary angles?
Yes. If two intersecting lines form the angles A, B, C and D (in rotational order) then AB, BC, CD and DA are pairs of supplementary angles.
What are lines that cross each other at exactly one point and form four angles?
Intersecting lines
How many angles are formed by two intersecting lines?
Four.
What are two lines intersecting to form two lines?
They would be called intersecting lines.Intersecting lines form Vertically Opposite Angles. Each pair of opposite angles (sharing only a vertex) is congruent. Each of the four pairs of adjacent (sharing a side) angles forms a straight angle (they add to 180o).
What is the sum of the measurements of the four angles formed by intersecting lines?
360
What is the sum of the measures of four angles formed by intersecting lines?
The angles will add up to 360 degrees
What is the sum of the measures of the four angles formed by intersecting lines?
The angles will add up to 360 degrees
Do 2 intersecting lines form four angels?
yes
How many angles less than 180 degrees each are formed by two intersecting lines?
Four and opposite angles are equal.
