Understanding different types of angles and that angles in a triangle sum to 180° can be helpful when classifying a triangle. Recognising line symmetry and rotational symmetry will also help. Look for ...

Big Idea – We can describe, measure, and compare spatial relationships. to build on students' knowledge of triangle and develop students' reasoning with properties of different classes of triangles to ...

The weak force is responsible for the decay of matter: unstable particles made of heavy quarks and antiquarks decay into particles made of their lighter cousins. The rates of these decay processes are ...

to build on students' knowledge of triangle and develop students' reasoning with properties of different classes of triangles to develop students' language related to different triangles to engage ...

Rotational symmetry-broken mechanism for simplifying exceptional point achievement. (a) 3D model of waveguide coupled RTR. (b) Field distribution and (c) far-field pattern of RTR at EP. The spectral ...

Figure 2: Time-averaged Fourier transforms and light scattering. In the T Δχ phase, the chiral symmetry is only broken locally: the system as a whole is a racemic mixture of small chiral domains. The ...
