How do you show that two line segments are congruent on a diagram?
To show that two line segments are congruent on a diagram, use a ruler or a compass to measure their lengths. If the segments are equal in length, you can mark them with the same number of tick marks (e.g., one tick for each segment) to indicate congruence. Additionally, you can label the segments with the same notation (e.g., AB ≅ CD) to emphasize their equality.
Which property is illustrated by the statement AB equals CD so AB plus DE equals CD plus DE?
It is the additive property of equality, as the additive property of length, as applied to adjacent or parallel line segments.
How do you draw a triangle with an area of 5 square units?
== == 1) Draw a line segment AB of 5 units 2) Draw the perpendicular bisector CD of AB such that Cd meerts AB at C. 3) Mark off CE = 2 units on CD 4) Draw the straight line segments AE & BE. ABE is your triangle. Its base (AB) = 5 and height (CE) = 2, so its area = [base x ht] / 2 = 5 sq units
If ec equals 9in. and CD in 130in. what does ed equal?
To find the length of segment ED, you can use the relationship between the segments if they are part of a geometric figure. If EC and CD are parts of a line segment where E, C, and D are collinear points, then ED can be calculated as ED = CD - EC. Substituting the given values, ED = 130 in - 9 in = 121 in. Therefore, ED equals 121 inches.
Slope of a line AB is 4 what is the slope of CD if CD is perpendicular to AB?
Slope of perpendicular line is the negative reciprocal. So it is -1/4
Can a geometry ray CD be called a DC?
No. Line CD is the same as line DC, but rays are always named from the origin point, so ray DC is a ray pointing in the opposite direction from ray CD.
What does it mean for something to be perpendicular?
For two items (Planes, lines, line segments, ect.) to be perpendicular that means that they meet at a 90 degree angle. Perpendicularity is denoted by the ⊥ symbol. For example line AB ⊥ line CD would mean that the line AB would be perpendicular to the line CD.
The segments that are congruent to segment GE?
segments AB, CD, BD.
What do you get when segments CD and RS dont intersect but rays CD and RS intersect?
cd rs
How many points do you need to name a ray segement?
Just like line segments or lines, you just need two points to name them. Line ---.-----.-----------------.--------------> A B C D Line= AB Line= BC Ray= CD
plot the given points in a coordinate plane. Then determine whether the line segments named are congruent. 1 A(0, 1), B(4, 1), C(1, 2), D(1, 6); line AB and line CD?
we can create a graph with the x-axis representing the horizontal values and the y-axis representing the vertical values. let's determine whether the line segments AB and CD are congruent. The length of line segment AB can be calculated using the distance formula: AB = sqrt((x2 - x1)^2 + (y2 - y1)^2) For AB(0, 1) and CD(4, 1), the length of AB is: AB = sqrt((4 - 0)^2 + (1 - 1)^2) = sqrt(16 + 0) = sqrt(16) = 4 For CD(1, 2) and CD(1, 6), the length of CD is: CD = sqrt((1 - 1)^2 + (6 - 2)^2) = sqrt(0 + 16) = sqrt(16) = 4 Since the length of AB is equal to the length of CD (both are 4 units), we can conclude that line segments AB and CD are congruent.
Explain why Ab and Ba are the same line but Cd and Dc are not not the same ray?
Ab and Ba are the same line because there are no endpoints to a line. Therefore, you can reverse the order of the letters. So, Cd and Dc are not the same ray because the first letter is the endpoint. So on ray Cd, point C is the endpoint and d is a point on the line coming from the endpoint. On ray Dc, D is the endpoint.
Which property is illustrated by the statement AB equals CD so AB plus DE equals CD plus DE?
It is the additive property of equality, as the additive property of length, as applied to adjacent or parallel line segments.
Why is ray CD the same as ray DC?
They define the same line segment, connecting two points.
Can CD be called a DC line segment?
Yes, it doesn't matter which end you start with when naming a line segment.
What is the new song that demi and the Jonas brothers duet with on her new CD?
It is called On The Line.
Suppose the slope of AB is zero what is the slope of CD given that a. CD is parallel to AB b. CD is perpendicular to AB?
Any line that is parallel to another line will have the same slope. So if line AB's slope is zero and line CD is parallel to AB, then its slope will also be zero. The slope of line CD, when perpendicular to AB, will be infinity. If line AB has a slope of zero that means its just a horizontal line passing some point on the y-axis. A line that is perpendicualr to this one will pass through some point on the x-axis and therefore have an infinite slope.
