add category in page

hi
I wrote code like this adds tabs. Now, I also want him to be classified. What should I do?

// teach post type
	$labelsTeach = array(
		'name' => '?????',
		'add_new' => '?????? ????',
		'add_new_item' => '?????? ????',
		'edit_item' => '?????? ????',
		'new_item' => '???? ???? ',
		'view_item' => '????? ????',
		'search_items' => '?????? ????',
		'not_found' => '???? ???? ???',
		'not_found_in_trash' => '???? ?? ????????? ???? ???',
		'menu_name' => '?????',
	);
	$argsTeach = array(
		'labels' => $labelsTeach ,
		'label' => '????? ',
		'hierarchical' => false,
		'description' => '?????',
		'supports' => array( 'title', 'editor' ) ,
		'public' => true,
		'show_ui' => true,
		'show_in_menu' => true,
		'menu_position' => 5,
		//'menu_icon' => get_template_directory_uri() . "/images/news.png",
		'show_in_nav_menus' => true,
		'publicly_queryable' => true,
		'exclude_from_search' => true,
		'has_archive' => true,
		'query_var' => true,
		'can_export' => true,
		'rewrite' => array('slug' => 'teach'),
		'_builtin' => false,
		'capability_type' => 'post'
	);

	register_post_type( 'teach', $argsTeach );
