two planes next to each other
A complex number, in my life, is a number which is composed of two parts: one part which is a real number and the other which is imaginary. It can be represented by a point in a coordinate plane.
On a coordinate plane, d^2=(y2-y1)^2+(x2-x1)^2 In a real life application d=speed x time
Well, honey, an acute triangle is any triangle where all three angles are less than 90 degrees. So, think of a slice of pizza or a traffic cone - those are acute triangles in the real world. Just keep your eyes peeled, acute triangles are everywhere, unlike a decent cup of coffee in a gas station.
Real life is a real life example!
The coordinate plane has helped people create graphs. With out graphs, we wouldn't be able to track stocks or display/compare information. The coordinate plane has also been a foundation for maps. The coordinate plane goes by (x,y), where a map goes by (letter, number) or (latitude, longitude). The coordinate plane is the reason we can find where a place is on the map. Because of this, satellites can also show us where we are on a gps and we can get directions via sateliite. The coordinate plane plays a big impact on our life.
In building construction, you usually have one horizontal plane (that floors) that is intersected by a vertical plane (the walls or support beams).
Well, there's always the map. Latitude, Longitude.
