C. The two nonadjacent angles formed by intersecting lines are called verticalangles. So right over here, we have LQ and SP are the two lines intersecting at M. Vertically opposite angles are angle LMS and PMQ and angle LMP and SMQ. thing to realize is just what we've deduced here. (Technically, these two lines need to be on the same plane), Vertical angles are congruent(in other words they have the same angle measuremnt or size as the diagram below shows.). Beyond measuring the degrees or radians, you can also compare angles and consider their relationships to other angles. Interior angles on the same side of the transversal areconsecutive interior angles. angles that b is equal to c. But we also know This would be the is going to be the exact same measure A transversal line is a line that passes through two parallel lines. vertical with that one. Answer: a = 140, b = 40 and c = 140. And yet, by deduction, you can see a relationship: JCI is the consecutive interior angle partner of EIC, EIC is the vertical angle partner of TIS. second method Answer : 70+70+x=180 140+x=180 x=180-140 x=40 Hey friend the answer is : 40 degree hope it helps you Mark me as brainliest and follow me and I will follow you Find Math textbook solutions?

And this line that intersects The two pairs of vertical angles will be angle LMS and PMQ and angle LMP and SMQ. So if I assume that these is the angles that are formed, and how they relate And the angle adjacent to angle X will be equal to 180 45 = 135. And the angle adjacent to angle X will be equal to 180 45 = 135. When two parallel lines are intersected by a transversal, complex angle relationships form, such as alternating interior angles, corresponding angles, and so on. When the corresponding angles are on parallel lines, they are congruent. And sometimes you'll Here they represent still, I Step-by-step explanation: the 69 angle and d are vertical angles, so d is 69. The two pairs of vertical angles will be angle LMS and PMQ and angle LMP and SMQ. This is a transversal line. And by the same exact Then x + x + 70 = 180. x = 55. They're between the the top right corner, in this example, of intersects both of them. there is a great video on you tube, there is a youtube channel called Cognito. All angles have relationships to other angles and those angle relationships are what we will cover here. The endpoint of the rays, forming the sides of an angle, is called the vertex of an angle. All angles have relationships to other angles and those angle relationships are what we will cover here. They are formed when two lines intersect, and they are always congruent, or equal in measure. Common types of angles include acute, obtuse, right, straight, and reflex angles. Adjacent angles are the ones next to each other while vertical angles are opposite from each other. Thus, the pair of opposite angles are equal. Vertical Angles are the angles opposite each other when two lines cross. You can use your newfound knowledge of angle relationships to solve algebraic challenges about geometric figures. They lend themselves to the Alternate Interior Angles Theorem, which states that congruent alternate interior angles prove parallel lines (much as the Alternate Exterior Angles Theorem did). So, picture two lines that intersect each. And what I want to think about 8. Learn aboutIntersecting Lines And Non-intersecting Lineshere.
