How do you know when lines are parallel on a graph?
How do you know when lines are parallel on a graph?
Parallel lines have the same slope and different y-intercepts. Lines that are parallel to each other will never intersect. For example, Figure 4 shows the graphs of various lines with the same slope, m = 2 \displaystyle m=2 m=2.
What does it mean when lines are parallel on a graph?
Parallel lines have slopes that are the same. All of the lines shown in the graph are parallel because they have the same slope and different y-intercepts. Lines that are perpendicular intersect to form a 90∘ angle. The slope of one line is the negative reciprocal of the other.
What are parallel graphs?
Parallel lines are a fixed distance apart and will never meet, no matter how long they are extended. Lines that are parallel have the same gradient . The graphs above, y = 2 x + 1 and y = 2 x − 2 have the same gradient of 2. The lines are parallel.
What angle do I cut to make an octagon?
22.5 degrees
How do you draw a perfect hexagon with a compass?
How to draw a hexagon using compass
- Step 1: Draw a circle. First draw a cross – two guidelines of the same length, crossing at a right angle (90 degrees).
- Step 2: Mark the top two corners. Next, we will mark the top two corners.
- Step 3: Repeat and mark the bottom two corners.
- Step 4: Connect the marked points to draw a hexagon.
How do you tell if a shape is concave or convex?
The difference between convex and concave polygons lies in the measures of their angles. For a polygon to be convex, all of its interior angles must be less than 180 degrees. Otherwise, the polygon is concave.
What are examples of convex?
Some examples of objects with convex lenses in include:
- Binoculars and telescopes.
- Cameras.
- Eye glasses.
- Flashlights.
- Lasers ( CD, DVD players)
What shape is concave?
Concave describes shapes that curve inward, like an hourglass. Convex describes shapes that curve outward, like a football (or a rugby ball).
What is an irregular four-sided shape called?
What is an irregular quadrilateral? Irregular quadrilaterals are: rectangle, trapezoid, parallelogram, kite, and rhombus. They are symmetrical, but are not required to have congruent sides or angles.
