“Travel a day, gain a sack of wisdom,” the journey to conquer mathematical knowledge is like climbing a mountain, each step we take opens up new horizons. Today, let’s join “HỌC LÀM” to break through your limits and explore the fascinating mysteries of advanced distance and angle geometry for grade 10!
Have you ever wondered how to calculate the distance between two skew lines in three-dimensional space? Or how to determine the angle between two seemingly unrelated planes? All will be revealed right here.

## The Geometry Universe: From Points to Space
In the world of geometry, points, lines, and planes intertwine, connecting to create a vast and fascinating universe. Mastering the concepts of distance and angle is like having a magic compass, guiding us to explore every corner of that universe.
### Distance: Footprints on the Sand
Imagine walking on a beach, each footprint in the sand is proof of a distance you have traveled. In geometry, it’s the same; distance is the measure of how far apart objects are. From the distance between two points, we can calculate the distance between a point and a line, between two lines, between a point and a plane, and so on.
### Angle: Fated Intersections
If distance tells us how far apart, then angle reveals the correlation between objects. The angle between two lines shows their “inclination” to each other, the angle between a line and a plane tells us the “slope” of the line, and so on.
## “Golden” Formulas Unlock the Door to Knowledge
Just like crafting keys, mathematicians have painstakingly researched, proven, and left us with “golden” formulas to solve problems about distance and angle.
The formula for calculating the distance from a point to a plane is like a “lucky charm,” helping us easily overcome challenging trials.
Or the theorem of two perpendicular lines is like a “magic door,” opening the door to new mysteries about the angle between two planes.
### Classic Problems – Keys to Success
To master the knowledge of advanced distance and angle geometry for grade 10, nothing is more effective than conquering classic problems. Let’s challenge ourselves with the problem of calculating the angle between two planes (SAC) and (SBD) in a pyramid S.ABCD with a rhombus base ABCD of side a, SA = SB = SC = a.
