1, Geometry: Geometry is one of the most important branches of mathematics in architecture. Architects need to use geometry to design the shape, size and proportion of buildings and ensure that they meet safety standards.

2. Trigonometry: Trigonometry is also one of the important branches of mathematics in architecture. Architects need to use trigonometry to calculate the equivalence of angle, distance and height in order to design the floor plan and three-dimensional structure of buildings.

3. Calculus: Calculus is widely used in architecture, such as calculating the structural mechanics and hydraulic efficiency of buildings.

4. Linear algebra: Linear algebra is used for building structure analysis, such as calculating the load and strength of beams and columns.

5. Statistics: Architects need to use statistics to predict the life of soil and buildings, building materials and costs. In architecture, mathematics is often used to solve various problems, such as structural design, spatial planning, material calculation and so on.
